Answer 2

Answer :

1) False

2) True

3) True

4) False

5) True

6) True

Explanation :

1) No, the laws of reflection do not change. They are applicable to spherical mirrors also.

The laws of reflection are valid for any reflecting surfaces including spherical surfaces . So , they are valid for both plane and curved mirrors .

2) Plane mirror always form virtual erect and laterally inverted image of unity magnification.

3)The angle of incidence is the angle between the incident ray and the normal to the reflector.

In the given figure, is the angle of incidence.

4) Light of different colours travel at different speeds in medium because wavelength of light depends on refractive index and so velocity also depends on refractive index.

5) White light is composed of seven colours: violet, indigo, blue, green, yellow, orange and red. This can be observed with the help of Newton's colour disc. It consists of the seven colours of white light.

6) it is true that light is a form of energy.
