What is meant by lateral inversion of an image in a plane mirror ? Explain it with the help of a diagram.
The reflection of light from a wooden surface is _________ reflection.
If the angle between the plane mirror and the incident ray is 40∘, what are the angles of incidence and reflection?
Explain the following term:
Reflected ray. Draw diagram/diagrams to show them.
Draw a diagram to show the reflection of a ray of light using a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.
An object 1.5 cm high when placed in front of a concave. the mirror produces a virtual image 3 cm high. If the object is placed at a distance of 6 cm from the pole of the mirror, calculate:
- the position of the image
- the focal length of the mirror.
In the figure is shown a concave mirror. A is a point on the principal axis. If an object O is kept at A, image is formed on A itself. Copy the diagram. Draw the image in the diagram. Is the image real or virtual?
Measure the distance PA and write it in the diagram. What is the distance PA called?
Mark a point B on the principal axis, at which, if a point source of light is kept, the rays travel parallel to principal axis after reflection from M. What is point B called?
Define reflection.
Suppose we wish to obtain the real image of a distant tree. Explain two possible ways in which we can do it.
