Question

The speed of light is 3×10^8m/s.Calculate the frequency of yellow light of wavelength 6×10^-7m

Answer 1

We know that frequency is 1/time, thus the unit is Hz (equal to s^-1). To calculate the frequency value, we use the equation Frequency = Wavespeed (m/s) / Wavelength (m). (This also provides a checking answer for the units).Thus the frequency = 310^8 / 5.810^-7 = 5.172*10^14 Hz
