Chapter 11: Introduction to Modern Atomic Theory

This video does a calculation.

Calculate the frequency of a sample of infrared radiation with a wavelength of 2500 nm.

The freqency of a sample of light with a wavelength of 2500 nm is 1.20 x 10¹⁴ sec^-1 (hertz). This is a large number, this number represents the number of crests of a wave which pass a point in space per second. This is a very large number.

The calculation demonstrated on this video is similar to the calcualtions you must do on PS14.2 and PS14.3.
