Question

What is the frequency of light having a wavelength of 413 nm?

Answer 1

Answer:

The required frequency = 7.263X10^14 Hz

Explanation:

We know,

Velocity of light in vacuum, v= 3X10^8 m/s

Given,

Wave length,λ= 413 nm= 4.13X10^-7 m

Now,

frequency, f= v/λ

                    = 7.263X10^14 Hz

∴ The required frequency = 7.263X10^14 Hz
