Reflection and Perception in Mirrors

The video tutorial explains how an image is formed when a candle is placed in front of a mirror. It describes the process of reflection, where incident rays from the candle hit the mirror and bounce back as reflected rays. The human eye perceives the image as coming from a straight line, not the actual V path of the rays. By extrapolating the reflected rays backward, the image appears to be behind the mirror. The tutorial uses diagrams to illustrate these concepts and concludes with a summary of the learning points.

What happens when you place a candle in front of a mirror?

• An exact image of the candle appears on the mirror.

• The candle changes color.

• The mirror becomes transparent.

• The candle disappears.

What are the rays called that come from the candle and hit the mirror?

• Reflected rays

• Refracted rays

• Incident rays

• Scattered rays

What is necessary to form an image on the mirror?

• A colored object.

• A transparent object.

• At least two rays from the object.

• One ray from the object.

What does the human eye perceive about the path of the image?

• It perceives the image as moving in circles.

• It sees the image as stationary.

• It perceives the image as coming from a straight line.

• It sees the image following a zigzag path.

Why can't the human eye trace the V path of the rays?

• Because the rays are too fast.

• Because the eye is not designed to trace V paths.

• Because the mirror distorts the rays.

• Because the rays are invisible.

What is the role of the human eye in perceiving images in a mirror?

• It perceives images as stationary.

• It perceives images as moving.

• It perceives images as distorted.

• It perceives images as coming from a straight line.

How is the image formed on the mirror according to the video?

• By changing the color of the rays.

• By bending the rays forward.

• By extrapolating the reflected rays backward.

• By rotating the mirror.

What does extrapolating the rays mean?

• Producing the rays backward.

• Bending the rays forward.

• Stopping the rays.

• Changing the color of the rays.

Where does the image appear to be formed when you look at a mirror?

• Behind the mirror.

• On the surface of the mirror.

• Above the mirror.

• In front of the mirror.

What did we learn about the reflection of objects in mirrors?

• Objects appear to be behind the mirror.

• Objects change color when reflected.

• Objects become larger in the mirror.

• Objects disappear when placed in front of mirrors.
