Calculate the wavelength of a photon which has a speed 1% of that of speed of light

Answer»

Answer:

The speed of light, c ,

equals the wavelength, λ

TIMES the frequency, ν

c =λν

c is a constant. It is USUALLY given as 3.00×10^8 m/s or 3.00×10^10 cm/s.

Frequency has a UNIT of 1/s

, which means 1 cycle per second. It is also given the unit Hertz (Hz) in HONOR of German physicist Heinrich Hertz who proved the existence of electromagnetic waves. 1Hz =1/s
