Physics of Light | MCQs

Explanation

Mirage is an example of:

• refraction of light
• total internal reflection

Example

When the reflected light ray reaches our eyes, it appears as coming from the sky or tree.

This inverted image creates an optical illusion of the presence of water or the presence of islands etc.

Explanation

Gamma rays are the highest energy photons, with energies typically above 100,000 electronvolts (eV).

They are a type of electromagnetic radiation, like X-rays and visible light, but with much shorter wavelengths and higher frequencies.
