Period = 1 / frequency = 1/100 = 0.01 second.

Frequency = reciprocal of period = 1 / 0.01 = 100per second = approximately 100 Hertz = roughly 100 cycles

Period = 1/ frequency So period = 1/100 = 0.01 second

Speed = (wavelength) x (frequency) = (10) x (100) = 1,000 meters per second

wave velocity = frequency in Hz x wavelength in meterSo frequency = 5 Hz and wavelength = distance between successive peaks = 20 cm = 20/100 mHence wave velocity = 5 * 20/100 = 1 m/s

Frequency = (speed) / (wavelength) = 900/9 = 100 Hz.

Since the wave speed equation tells us that the speed of a wave (meters per second)is equal to the wavelength (meters) multiplied by the wave frequency (Hertz), you should be able to calculate your answer by multiplying 12 and 100. Don't forget to include the units that your answer will be measured in!

The frequency is 15 MHz.

It means that the wave (or Object) in reference is repeating itself with the rate of 100 Cycles (or times) per second.

It completes 20 vibrations per second, the the period is 1/20 of a second.

If an electromagnetic wave has a frequency of 100 Hz, then its wavelengthin vacuum is almost 1,900 miles, and we would call it a radio wave in the ELF(extremely low frequency) range.

Please use the equation: speed (of the wave) = frequency x wavelength ===================== 5Hz
