3.25 x 10¹⁴m
Explanation:
Given parameters:
Frequency of the radiation = 9.23 x 10⁻⁷hz
Unknown:
Wavelength of the radiation = ?
Solution:
The velocity of electromagnetic radiation is the same as that of the speed of light in vacuums.
Velocity = frequency x wavelength.
Velocity = 3 x 10⁸m/s
Since the unknown is wavelength, we factor it out:
Wavelength =
Wavelength =
= 3.25 x 10¹⁴m
