Calculate the frequency and energy of photon having wavelength of 6000

1.	Calculate the frequency and energy of photon having wavelength of 6000°A
Answer» Wavelength = 6000 Å = 6 × 10^-7 m. V = 3 × 10^8 m/s. Therefore, frequency = v/wavelength = 3 × 10^8 / 6 × 10^-7 = 0.5 × 10^15 Hz. //Energy = hv/wavelength = 6.626 × 10^-34 × 0.5 × 10^15 = 3.313 × 10^-19 J. //
