Question

Calculate the frequency of visible light having a wavelength of 4461 nm.
tion:

Answer 1

Frequency =0.67×10¹⁴ Hz

Step-by-step explanation:

Given data:

Wavelength = 4461 nm

Frequency = ?

Solution:

Wavelength = 4461 nm /10⁹ = 4.461×10⁻⁶m

Formula:

speed of light = wavelength× frequency

speed of light = 3×10⁸ m/s

Now we will put the values in formula.

3×10⁸ m/s = 4.461×10⁻⁶m × frequency

Frequency = 3×10⁸ m/s / 4.461×10⁻⁶m

Frequency =0.67×10¹⁴ s⁻¹

s⁻¹ = Hz

Frequency =0.67×10¹⁴ Hz
