Answer:

option b is correct option = (6.76×10¹⁴ Hz)

Step-by-step explanation:

Given data:

Wavelength of photon = 4.42×10⁻⁷ m

Speed of light = 2.99×10⁸ m/s

Frequency of radiation = ?

Solution:

Formula:

Speed of wave = frequency × wavelength

Now we will rearrange this formula.

frequency = Speed of wave / wavelength

f = c/ λ

f = 2.99×10⁸ m/s / 4.42×10⁻⁷ m

f = 0.676×10¹⁵ Hz (s⁻¹ = Hz)

f = 6.76×10¹⁴ Hz

Thus option b is correct option.
