Is it true or false The strength of an electrical signal is directly proportional to to its frequency?
False. The strength of an electrical signal is not directly proportional to its frequency. The strength of an electrical signal is related to its amplitude, which is the height of the signal. Frequency, on the other hand, refers to the number of cycles of the signal that occur in a given unit of time.
The unit of the period of a wave is the hertz True Or False?
False. The unit of the period of a wave is seconds, not hertz. Period is the time it takes for one complete cycle of the wave, while hertz represents the frequency of the wave, which is the number of cycles per second.
True or false if the wavelength of a given wave decreases you know that its frequency will stay the same?
False. The frequency of a wave and its wavelength are inversely proportional - as the wavelength decreases, the frequency increases, and vice versa.
The wavelength of light is very long and the frequency is very short true or false?
False. The wavelength of light is inversely related to its frequency. Longer wavelengths have lower frequencies and vice versa.
Is it True Or False The Period of the wave is directly proportional to its frequency?
True. The period of a wave is inversely proportional to its frequency. That means as the frequency of a wave increases, the period of the wave decreases proportionally.

False. The unit of the period of a wave is seconds, not hertz. Period is the time it takes for one complete cycle of the wave, while hertz represents the frequency of the wave, which is the number of cycles per second.
Is it true or false that in frequency modulations the frequency of the carrier signal is modified by the application of the data signal?
True.
Is this true or false The whistle of a teakettle has a greater frequency than a drumbeat?
True.
True or false if the wavelength of a given wave decreases you know that its frequency will stay the same?
False. The frequency of a wave and its wavelength are inversely proportional - as the wavelength decreases, the frequency increases, and vice versa.
True or false The allele for sickle cell anemia is slowly increasing in frequency in the US?
false
A grouped frequency distribution is used when the range of data values is relatively small. True or false?
False. When the range is large you would use a grouped frequency distribution.
True or false does the heart beats fifty times a minutes?
false
Some electrons in atoms vibrate at a characteristic frequency that produces white light True Or False?
False. White light is produced when a combination of different frequencies of light are present together. Each electron vibration at a characteristic frequency would produce a specific color of light, rather than white light.
Is it true or false that 2 minutes equals 120 seconds?
True
A change in gene frequency in a population over time is a foundation of biological evolution true or false?
True. That is the definition of evolution.
The wavelength of light is very long and the frequency is very short true or false?
False. The wavelength of light is inversely related to its frequency. Longer wavelengths have lower frequencies and vice versa.
