Question

Determine the frequency of light with a wavelength of 4.50 x 10-7 m.

Answer 1

f = 0.67×10¹⁵ s⁻¹

Step-by-step explanation:

Given data:

Frequency of light = ?

Wavelength = 4.50 ×10⁻⁷ m

Solution:

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 = 4.50 ×10⁻⁷ m × f

f = 3×10⁸ m/s / 4.50 ×10⁻⁷ m

f = 0.67×10¹⁵ s⁻¹
