Science- Physics- Light Reflection and Refraction Online Practice Exams FAQs

1. What is reflection of light?

Reflection of light is the phenomenon where light rays bounce off a surface, changing their direction of propagation. When light strikes a smooth surface, such as a mirror or still water, the incident light rays are reflected at the same angle at which they hit the surface, obeying the law of reflection. This results in the formation of a reflected image. Reflection plays a crucial role in our daily lives, enabling us to see objects and providing the basis for mirrors, reflective surfaces, and optical devices like telescopes and periscopes.

2. What is refraction of light?

Refraction of light is the bending of light rays as they pass from one transparent medium to another, due to the change in the speed of light. When light travels from a rarer (less dense) medium to a denser medium, it bends towards the normal (an imaginary line perpendicular to the surface of separation). Conversely, when light travels from a denser medium to a rarer medium, it bends away from the normal. This bending of light is responsible for phenomena such as the apparent displacement of objects in water, the bending of a pencil in a glass of water, and the formation of rainbows in raindrops.

3. What is the difference between regular and irregular reflection?

Regular reflection occurs when parallel incident light rays strike a smooth and polished surface, resulting in parallel reflected rays. This type of reflection produces a clear and sharp image, such as the reflection in a mirror. On the other hand, irregular reflection occurs when incident light rays strike a rough or uneven surface, causing the reflected rays to scatter in different directions. Irregular reflection does not produce a clear image and is responsible for the diffuse reflection of light, as observed from surfaces like paper, walls, or rough objects.

4. What is the critical angle in optics?

The critical angle in optics refers to the specific angle of incidence at which light passing from a denser medium to a rarer medium undergoes total internal reflection. When the angle of incidence exceeds the critical angle, no refraction occurs, and all the incident light is reflected back into the denser medium. The critical angle depends on the refractive indices of the two media involved and can be calculated using Snell's law. The phenomenon of total internal reflection is utilized in various applications, including fiber optics, prism-based optical devices, and diamond's sparkle due to its high refractive index.

5. What is the difference between concave and convex mirrors?

Concave and convex mirrors are curved mirrors with different characteristics:

A concave mirror is thicker at the center and thinner at the edges. It curves inward, and the reflecting surface is on the inner side of the curve. Concave mirrors can produce both real and virtual images, depending on the object's position relative to the focal point.
A convex mirror is thinner at the center and thicker at the edges. It curves outward, and the reflecting surface is on the outer side of the curve. Convex mirrors always produce virtual and diminished images of objects, irrespective of the object's position.

Concave mirrors are commonly used in applications like shaving mirrors, telescopes, and headlights, while convex mirrors are used in rearview mirrors, security mirrors, and camera lenses.
