4. Bending of light through atmosphere

Question:

4 m.

Answer the questions given below:

A student observes a distant object through the air rising above a fire. The image of the object appears to shift irregularly, even though the object itself remains stationary. The effect becomes less noticeable when the air movement settles down.

1. Which of the following phenomena explains the observed effect?

Reflection of light
Dispersion of light
Atmospheric refraction
Scattering of light

2. Which change in the air near the fire contributes to this phenomenon?

The air becomes colder and denser
The air stops transmitting light
The air becomes hotter and less dense
The air acquires a uniform refractive index

3. Why does the image appear to shift irregularly?

The object emits light intermittently
The object changes its actual position
The optical conditions along the light path change continuously
The light is separated into different colours

4. This observation demonstrates an optical phenomenon occurring:

exclusively during nighttime
on a small scale in the local environment
only in outer space
only in a vacuum
