Because the speed of the wave usually is the same for different frequencies (or wavelengths). The basic formula is: c = (lambda) f - the speed of the wave is equal to the wavelength times the frequency. For example, the speed of light is 300,000 km/sec; if two wave crests pass by you every second (frequency = 2 Hz), then the distance from one wave crest to the next is 150,000 km.
When a wave changes frequency, its wavelength also changes because the speed of the wave remains constant. This relationship is defined by the wave equation: speed = frequency x wavelength. Therefore, if the frequency increases, the wavelength must decrease to maintain a constant speed.

What would be an observable change in sound when the frequency changes?
An observable change in sound when the frequency changes is a difference in pitch. As the frequency increases, the pitch becomes higher, and as the frequency decreases, the pitch becomes lower. This change in pitch is due to the direct relationship between frequency and pitch in sound waves.
Sound change in frequency due to motion?
The Doppler effect is the change in frequency of sound waves as a sound source or listener moves relative to each other. When a source is moving towards a listener, the frequency appears higher (shorter wavelength) due to compression of waves. When moving away, the frequency seems lower (longer wavelength) due to stretching of waves.
What causes the frequency of a wave to change?
The frequency of a wave can change due to the motion of the source or observer relative to each other, known as the Doppler effect. Additionally, a change in the medium through which the wave is traveling, such as a change in its density or temperature, can also cause the frequency of the wave to change.
Does the wave speed change in the Doppler effect?
No, the wave speed does not change in the Doppler effect. The apparent frequency and wavelength of the wave change due to the motion of the source or observer relative to the wave, but the speed of the wave remains constant.
What do you call the change in sound frequency due to a relative motion?
The Doppler Effect.

Why an inductor opposes the flow of alternating current?
A change in current through an inductor will induce a voltage into that conductor, the direction of which will always oppose that change in current. This is a natural phenomenon due to the conservation of energy.
If the bug in the demonstration moves forward does the speed of the waves change. What does change?
The speed of the wave stays same but the frequency change due to motion.
What do you call the change in sound frequency due to a relative motion?
The Doppler Effect.
How does the amplitude change as the frequency increases?
As the frequency increases, the amplitude of a wave remains constant if the system is linear. In non-linear systems, the amplitude may change as the frequency increases due to factors such as resonance or saturation effects.
A change in pitch or wave frequency due to a moving wave source is an instance of the?
Doppler effect. This phenomenon describes the change in frequency or pitch of a wave when the source of the wave is in motion relative to the observer.
What is the change in frequency of a sound due to motion of the source?
The change in frequency of a sound due to motion of the source is called the Doppler effect. If the source is moving towards the observer, the frequency of the sound appears higher (blueshifted), while if the source is moving away, the frequency appears lower (redshifted). This effect is commonly experienced with passing vehicles and sirens.
What is function of emitter bypass capacitor?
A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly
Does the frequency change when it is moved from air to water?
Yes, the frequency of a wave changes when it transitions from air to water because the speed of the wave changes due to the different medium. In general, the frequency remains constant as it transitions, but the wavelength and speed change, resulting in a different propagation direction and angle.
