Question

1. While the wavelength of light decreases (the frequency of light increases), what happened to the speed of the ejected electrons? The speed of electrons represents the energy of light. What conclusion can you draw about the relationship of the energy of light and the frequency of light? Is your conclusion consistent with Planck equation: E = h? E is energy of light,  is frequency of light.

Expert Solution

Step 1

The Planck's equation is given as follows:

$E = h v$

Where,

E is energy of photon
h is Planck's constant
v is the velocity

It can be expressed as follows:

$E = h \frac{c}{λ}$

Where,

$λ$ is wavelength of light
c is speed of light
