Explain the laws of reflection and refraction.

<p>The law of reflection states that the angle of incidence is equal to the angle of reflection, and the incident ray, the normal, and the reflected ray lie in the same plane. The law of refraction states that the incident ray, the refracted ray, and the normal to the interface of two media at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, known as the refractive index.</p> Signup and view all the answers

Explain mirage effect.

<p>The mirage effect is an optical illusion caused by the bending of light rays due to temperature variation in different layers of air. When the ground is significantly hotter than the air above it, the light rays bend away from the denser cooler air, creating a displaced image of the sky or distant objects on the horizon. This creates the illusion of water or a pool of liquid on the ground, which is known as a mirage.</p> Signup and view all the answers
