Reflection 

Definition of Reflection:

When a light ray is obstructed by any solid surface it will reflect back from the surface, as it cannot pass through the surface.

Light ray will be reflected with the same angle with which it is falling on the surface.

What law describes the angle of incidence being equal to the angle of reflection?

1. Snell's law
2. The law of reflection
3. Newton's law of motion
4. The law of refraction

Why is the Law of Reflection important?

1. Predicts light ray deflection accurately.
2. It only applies to flat surfaces.
3. It only applies in dark rooms.
4. It has no applications in science.

What does the normal represent?

1. The direction of light.
2. The angle of incidence.
3. The angle of reflection.
4. An imaginary perpendicular line.

What surfaces does the Law of Reflection apply to?

1. Only flat mirrors.
2. Only curved mirrors.
3. Opaque surfaces only.
4. Flat and curved mirrors.

What is the angle of incidence measured from?

1. The normal line to the surface.
2. The edge of the mirror.
3. The centre of the mirror.
4. The direction of the light source.

What does the Law of Reflection state?

1. Angle of incidence is always 90 degrees.
2. Angle of incidence equals angle of reflection.
3. Reflection occurs without any angle.
4. Angle of incidence is double the reflection.
