 Reflection of
light
- What is meant by Reflection of light?
When a ray of light hits the surface of an object, part of the
light is absorbed and part is reflected.
- What is meant by normal?
If we draw a line perpendicular to a surface, this line is the
normal of the surface.
- What is meant by the incident angle?
Is the angle between the normal and the
incident ray.
- What is meant by the reflection angle?
Is the angle between the normal and the
reflected ray.
- State the reflection law of light?
1- The incident ray of light, normal, and reflected ray are in
the same plane
2- The reflection angle is equal to the incident angle
- What are the characteristics of an image in a plane mirror?
- The image has the same size as the object
- The image distance from mirror is the same as the object distance from mirror
- The image distance from the object is twice the distance from the mirror to the object
- The image is virtual and upright
- The image is laterally inverted
- Explain how to draw the image of an object in a plane mirror?
- Draw a line from the most top point in the object that is perpendicular to mirror
- Draw a line from the most top point in the object that is makes an angle with the Normal to mirror
- Draw a line from the lowest point in the object that is perpendicular to mirror
- Draw a line from lowest point in the object that is makes an angle with the Normal to mirror
