Reflection and Refraction of Light: Law Of Reflection

The video tutorial explains the concept of light reflection, focusing on how light rays bounce off surfaces like mirrors. It introduces key terms such as incident ray, reflected ray, and normal. The law of reflection is discussed, stating that the angle of incidence equals the angle of reflection. A practical example with a candle and mirror illustrates these concepts, emphasizing that the incident ray, normal, and reflected ray lie on the same plane.

What is the term used for the line that is perpendicular to the reflecting surface?

• Normal

• Incident ray

• Plane

• Reflected ray

According to the law of reflection, what is true about the angles of incidence and reflection?

• They are always different.

• They are equal.

• They are complementary.

• They are supplementary.

When a lighted candle is placed in front of a mirror, how do the light rays behave?

• They are absorbed by the mirror.

• They reflect at angles equal to their angles of incidence.

• They pass through the mirror.

• They scatter randomly.

What do Theta I and Theta R represent in the context of reflection?

• The angles of incidence and reflection.

• The intensity of light and shadow.

• The speed of light and sound.

• The distance from the mirror and the object.

In the context of reflection, which of the following is true about the incident ray, the normal, and the reflected ray?

• They intersect at different points.

• They lie on different planes.

• They are parallel to each other.

• They lie on the same plane.
