Answer 1

Explanation:

here is your ans. it's too simple

Answer 2

Given:

The wavelength of light is $4.06×10^{-11}$ meter.

To find:

The energy of the light.

Solution:

To determine the energy of the light we have to follow the below formula as follows-

The energy is given as-

E=hc/q.

Where h is the Plank's constant =$6.6×10^{-34}$.

c is the speed of the light= $3×10^{8}$.

q is the wavelength of the light =$4.06×10^{-11}$.

Thus, the energy of the light is as follows-

$E = \frac{6.6 \times {10}^{ - 34} \times 3 \times {10}^{8} }{4.06 \times {10}^{ - 11} } \\ E = 4.87 \times {10}^{ - 15}$

The energy of the light is $4.87 \times {10}^{ - 15}$.
