Name:
1. If an X-ray machine emits E.M.R with a wavelength of 2.15 x 10
-10
meters, what is the frequency?

Answer 1

The frequency of the emitted E.M.R is 1.395 x 10^18 Hz.

Step-by-step explanation:

In order to find the frequency, we can use the formula: λ = c/f, where λ is the wavelength, c is the speed of light, and f is the frequency. Solving for f, we get: f = c/λ. Plugging in the given values, with c being the speed of light (3 x 108 m/s) and λ being 2.15 x 10-10 meters, we can calculate the frequency as follows: f = (3 x 108 m/s)/(2.15 x 10-10 meters) = 1.395 x 1018 Hz.
