Answer(a) is CORRECT
(b) f = speed/wavelength. Since we are dealing with photons, the speed is the speed of light =>
f = 3x10^8 / 6.3x10^-7 = 4.8x10^14 Hz
(c) E = hf (h is the Planck's constant)
(b) f = speed/wavelength. Since we are dealing with photons, the speed is the speed of light =>
f = 3x10^8 / 6.3x10^-7 = 4.8x10^14 Hz
(c) E = hf (h is the Planck's constant)
