When light travels from a rarer to denser medium, it loses some speed. Does the reduction in speed imply a reduction in the energy carried by the light wave ?

Explanation

To determine whether the reduction in speed of light when it travels from a rarer to a denser medium implies a reduction in the energy carried by the light wave, we can analyze the relationship between speed, frequency, wavelength, and energy.

### Step-by-Step Solution:

1. **Understanding the Mediums**:
- Light travels from a rarer medium (like air) to a denser medium (like glass). In the rarer medium, the speed of light is at its maximum, denoted as \( c \).

**Hint**: Identify the characteristics of rarer and denser mediums and how they affect light.
