To make sound frequency change alter the pitch.
the frequency of a sound can change depending on how fast the source is vibrating
i think it is D. make no change
gthgh
the number of vibrations made by the vibrating body in one second is known as its frequency
More details are necessary to answer this question
True.
freq is reciprocal if time period... f= 1/timeperiod H.. in 1 unit of time number of oscillations made is defined as frequency...
The product of (wavelength) times (frequency) is always the same number ... the wave's speed. So if one of them doubles, the other one must drop by half.

the number of vibrations made by the vibrating body in one second is known as its frequency
FM or frequency modulation is a means to vary the frequency withing a set basic frequency and transmit it. FM radio demodulate the frequency extracting the signal that made the frequency shift at the source.
at microwave frequency why should the transmission line may considered to be made of unit length?
The number of circular revolutions made by the charged particle in one second. f=1/T unit of frequency is Hertz
The sound made by a wave depends on frequency and amplitude.
More details are necessary to answer this question
True.
Its frequency.
noise and frequency are made a vibration
The answer is "it's own resonant frequency".. this frequency is dependent on how the glass is made. You can hear this frequency when you rim the glass with a wet finger or smack it with a pen. If you want to break it, place the glass next to a nice speaker, generate a sine-wave tone matching the resonant frequency, and turn it up to 11.
