Suppose a bug is jiggling up and down and swimming towards you at the same time compared to the frequency at which the bug is emitting waves the frequency of the wave reaching you is?
The frequency of the waves reaching you is higher then.
When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
What is a fundamental mode of vibration?
The fundamental frequency is the lowest mode of vibration of a system. If you think of a taut string, the lowest mode with which it can vibrate is the one where the centre of the string travels the maximum distance up and down so the string forms a single arc. It is also possible for it to vibrate so that two arcs (one up and one down) fit into the string, and there are many more possibilities with higher frequencies. On a stringed instrument you can hear the fundamental frequency as the normal note which the string plays, and the others as overtones. Other systems exhibit the same phenomenon.
What is the number of cycles per second in a sound wave?
what is being asked for in this question is "frequency(f)", but in order to answer to answer this question, there is need to know the velocity of this sound wave and its wave length. since there are non of these mentioned in the question, i will give my own values, let the velocity be 330m/s which is the speed of sound in air and let the wave length be 30m. therefore f=velocity/wave length: which gives f=330m per second/30m = 11 hertz
The hertz is used to measure the frequency of sound if something is rated at 150 hertz what does that mean?
That means that whatever that wave is, whether it be a radio or television wave, is moving up and down 150 times per second.
What parts make up a sound wave?
A sound wave is made up of three main parts: frequency, wavelength, and amplitude. Frequency refers to the number of complete cycles of the wave that pass a point in a certain amount of time. Wavelength is the distance between two consecutive points of the wave that are in phase. Amplitude is the measure of the strength or intensity of the wave.
What makes up a wavelength in a compressional wave?
A wavelength in a compressional wave represents the distance between two successive points in a wave that are in phase. In a compressional wave, such as a sound wave in air, the wavelength is determined by the distance between two consecutive compressions or rarefactions in the medium through which the wave is propagating.
If the energy of a wave goes up does the frequency go down?
No, the frequency of a wave is determined by the number of wave cycles that pass a fixed point in a given unit of time, and is not directly related to the energy of the wave. An increase in energy does not inherently affect the frequency of the wave.
What wave is made up of a series of compressions and rarefactions?
A sound wave is made up of a series of compressions and rarefactions. In a compression, particles are close together, while in a rarefaction, particles are spread out. Sound waves travel by vibrating molecules and transferring energy through a medium like air or water.
What happens to the frequency of a wave when the wavelength goes up?
When the wavelength of a wave goes up, the frequency of the wave goes down. This is because the frequency and wavelength of a wave are inversely proportional; as one increases, the other decreases.
What is fundamental wave?
A fundamental wave is the lowest frequency or simplest wave form that makes up a complex wave. It is a pure tone without any harmonics or overtones. In music, the fundamental wave corresponds to the pitch or note that we hear.
What would happen to the wave length if you could increase the frequency of a periodic wave?
If you increase the frequency of a periodic wave, the wavelength would decrease. This is because wavelength and frequency are inversely proportional in a wave: as frequency goes up, wavelength goes down.
Does frequency change when you turn up the volume?
No, turning up the volume does not change the frequency of a sound wave. The frequency of a sound wave is determined by the rate of vibrations, while the volume is related to the amplitude of the wave, which increases the intensity of the sound.
A cork floats on the water as a wave passes by What happens to the cork Will the cork's vibrational frequency be related to the water wave's frequency and if so how?
The cork will move up and down with the passing wave, but it will still remain on the surface. The cork's vibrational frequency can be related to the water wave's frequency if the wave causes the cork to vibrate at a similar rate as the wave passing by. This phenomenon is known as resonance, where the cork absorbs energy from the passing wave, causing it to vibrate at the same frequency.
How you could model a compressinal wave by using a coiloed-spring toy?
To model a compressional wave using a coiled-spring toy, you can compress one end of the toy causing the coils to bunch up together. When released, the energy will travel through the coils in a wave-like motion resembling a compressional wave. As the coils expand and contract, they represent the alternating compressions and rarefactions of the wave.
If the frequency of a wave increases what does that do to waves wavelenght?
If the frequency of a wave increases, the wavelength decreases. This is because there is an inverse relationship between frequency and wavelength in a wave - as one goes up, the other goes down.
What happens to the frequency when the wavelength of an electromagnetic wave goes up?
As wavelength goes up, the frequency comes down.
