Why is the amount of the momentum transferred by the em waves incident on the surface so small?

Explanation

To understand why the amount of momentum transferred by electromagnetic (EM) waves incident on a surface is so small, we can analyze the relationship between momentum, energy, and the speed of light. Here’s a step-by-step solution:

### Step 1: Understanding Momentum of EM Waves
The momentum \( P \) of electromagnetic waves can be expressed in terms of the energy \( E \) of the waves and the speed of light \( c \):
\[ P = \frac{E}{c} \]
This equation indicates that the momentum is directly proportional to the energy and inversely proportional to the speed of light.
