1. Calculate the frequency of light with a wavelength of 2914 nm. What type of electromagnetic radiation has a wavelength of 2914 nm (i.e. gamma rays, microwaves,etc.) 2. C. Calculate the energy of a single photon and wavelength of light if the light has a frequency of 2.451 x 1020 s–1. What type of electromagnetic radiation has a frequency of 2.451 x 1020 s–1(i.e. gamma rays, microwaves,etc.) 1. Calculate the frequency of light with a wavelength of 2914 nm.

What type of electromagnetic radiation has a frequency of 2.451 x 1020 s–1(i.e. gamma rays, microwaves,etc.)Explanation / Answer
1.)
Convert nm to m:
2914 nm x (1 m / 109 nm) = 2.914 x 10¯-6 m
Substitute into = c:
(2.914 x 10¯-6 m) (x) = 3.00 x 108 m s¯1
x = 1.0295 x 1014 s¯1
Hence, frequency is 1.0295 x 1014 s¯1 and it is type of electromagnetic radiation is Infrared radiation.
2.) E = hv
Here, v = 2.451 x 1020 s–1. ,
h = 6.626176 x 10-34 Js
E = 2.451 x 1020 X 6.626176 x 10-34 = 1.624 X 10-13 J
Hence, energy of a single photon = 1.624 X 10-13 J
Type of electromagnetic radiation is Gamma rays.
