Which of the following statement is or are correct?
Consider the following statements and choose the incorrect one:
Badal appeared in class test but he confused to know the correct statement. Would you help him to know that?
These days New Cartesian Sign convention is used for measuring the various distance in the ray diagrams of spherical mirror. Choose the correct statements:
A ray of light is incident on a plane mirror making an angle of 90° with the mirror surface. The angle of reflection for this ray of light will be:
The image formed by a plane mirror is:
An object is placed 20 cm in front of a plane mirror. The mirror is moved 2 cm towards the object. The distance between the positions of the original and final images seen in the mirror is:
Linear magnification produced by a concave mirror may be:
Magnification produced by a rear-view mirror fitted in vehicles
A full-length image of a distant tall building can definitely be seen by using
What do you know about the diffraction of light?
If an opaque object on the path of light becomes very small, light has a tendency to bend around it and not walk in a straight line – an effect known as the diffraction of light.
Why do we use Convex mirrors as rear-view mirrors?
Convex mirrors are normally used as rear-view mirrors in vehicles. These mirrors are preferred because they always give an erect image. They have a wider field of view as they are curved outwards. In this way, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
What is Snell’s law of refraction?
During the refraction of light, the ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given colour and for the given pair of media. This law is also known as Snell’s law of refraction.
What is meant by Power of a Lens?
The ability of a lens to converge or diverge light rays depends on its focal length. The power of a lens is defined as the reciprocal of its focal length.
