2. Three characteristic of an image formed by plane mirror
3. What is lateral inversion?
4. Name two phenomena which can be explained by considering Particle nature and wave nature of light separately.
Answers
Explanation:
1) The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray.
2) The three characteristics of image formed by a plane mirror :
Image formed by are upright or erict.
Images formed are virtual.
Images formed are of the same size of the object.
3) If an object is placed in front of a plane mirror, then the right side of the object appears to be the left side of the image, and the left side of the object appears to be the right side of its image. This change of sides of an object and its mirror image is called lateral inversion.
4) The two phenomena are usually quoted demonstrating the particle of light : 1) The photo electric effect and 2) The compton scattering of X-rays.
