Reflection and Ray Diagrams

The video tutorial explains how ray diagrams are used to describe the reflection of waves from surfaces. It covers the basics of drawing ray diagrams, identifying the normal, and measuring angles of incidence and reflection. The tutorial also demonstrates the application of these principles to reflection in plane mirrors, showing how to find the image location by extending reflected rays behind the mirror.

What is the angle between the incident wave and the normal called?

• Angle of deviation

• Angle of reflection

• Angle of refraction

• Angle of incidence

According to the law of reflection, how does the angle of incidence compare to the angle of reflection?

• It is unrelated

• It is always greater

• It is always less

• It is equal

What tool is used to measure the angle of incidence in ray diagrams?

• Protractor

• Compass

• Ruler

• Set square

In a plane mirror, what is the side called where reflection is considered?

• Shaded side

• Non-reflective side

• Reflective side

• Opaque side

How can the image location be determined in a plane mirror?

• By calculating the angle of incidence

• By using a magnifying glass

• By drawing dotted lines from reflected rays behind the mirror

• By measuring the distance from the mirror
