Two monochromatic beam A and B of equal intensity I, hit a screen. The number of photons hitting the screen by beam A is twice that by beam B. Then what inference can you make about their frequencies?

Explanation

To solve the problem, we need to analyze the relationship between the intensity of the beams, the number of photons, and their frequencies.

### Step-by-Step Solution:

1. **Understanding the Given Information**:
- Let \( N_A \) be the number of photons from beam A.
- Let \( N_B \) be the number of photons from beam B.
- We are given that \( N_A = 2N_B \) (the number of photons from beam A is twice that from beam B).
