Question

if wave length of uisible light is very from 4000A° to 8000A° then calculate uisibly light​

Answer 1

Answer:

Answer

Speed of electromagnetic wave v=3×10

8

m/s in vacuum.

Frequency of wave ν=

λ

v

⟹ ν∝

λ

1

(∵v=same)

This means higher the wavelength of light, lower is the frequency.

Thus 4000 A

o

light has higher frequency than 8000 A

o

light.
