Question

A laser emits light with a frequency of 5.69 x 1014 s-1. the energy of one photon of the radiation from this laser is:_________

Answer 1

The radiation from this laser is 3.7 x 10^(-19)

Calculation

here ∨ = 5.69 x 10^(14) s-1

we know E=h∨

where h = 6.626 x 10^(-34) js

putting the value in the formula, we have,

6.626 x 10^(-34)  x 5.69 x 10^(-34)

=3.7 x 10^(-19)

What is radiation?

The energy emission in the form of electromagnetic waves or in the form of moving subatomic particles which are especially high-energy particles which cause ionization is called as the phenomenon of radiation.

Any kind of energy that emanates from a source and moves through space at the speed of light is referred to as radiation. This energy has wave-like qualities and is accompanied by an electric field and a magnetic field.
