What is the energy of a blue photon of wavelength 400 nm?

Solution: From the previous problem, the energy of a single 400 nm photon is

3.1 eV

. One must therefore reduce the effective work function to 3.1 eV to allow the light to liberate an electron.

What is the wave number equivalent of 400 nm wavelength?

Thus, the wave number will be equal to.

(1) 2.5 x 104 cm-1

.

How do you calculate the energy of a photon of blue light?

Explanation: To find energy, you must know the frequency of the light. Since we are given wavelength we can use this equation:

c= λ v

where c is the speed of light (3 x 108 m/s), λ is the wavelength, and the v is the frequency (units: 1/s).

What is the energy of blue light with a wavelength of 500 nm?

The energy of a 500 nm photon is

4 x 10^-19 J

.

Is Red light slower than blue light?

Blue light travels slightly slower in glass than red light

, so it bends a sharper angle when it enters the glass from air. In physics, we say the glass has a higher refractive index for blue light than red light.
