Assuming the minus sign is spurious, the answer is given in the question: frequency = 5 Hz.
365 Hz or 375 Hz.
5cm equals 2in.
1/5 Hz
375 Hertz or 365
if the cycle lasts 5 seconds, then the frequency is 0.2 Hz
Frequency = 1/(time period) so frequency = 1/5 =0.2 Hz
It is: 4*5 = 20cm
what is the energy of a photon that has a frequency of 5.0x1014 Hz?
The answer is in the question! 5 Hz Also, a wavelength cannot be 5 cycles - wrong units.
For a wavelengt lambda in air with the speed of sound of c = 340 meters per second the frequency f: f = c / lambda. A wavelength of 5 meters equals a frequency of 68 Hz. A wavelength of 0.2 meters equals a frequency of 1700 Hz. There is a useful calculator for converting wavelength to frequency and vice versa.
