Question

radio waves, microwaves, and infra - red waves are on the low energy side of the electromagnetic spectrum. do they have a high or low frequency? high low

Explanation:

Step1: Recall energy - frequency relation

The energy of an electromagnetic wave is given by \(E = h
u\), where \(h\) is Planck's constant (\(h= 6.626\times10^{-34}\space J\cdot s\)) and \(
u\) is the frequency of the wave.

Step2: Analyze the given situation

Since radio waves, microwaves, and infra - red waves are on the low - energy side of the electromagnetic spectrum. Given \(E = h
u\), when \(E\) is low (for a non - zero \(h\)), \(
u\) (frequency) must be low.

Answer:

LOW
