Answers
Answer:
1) Basis of Comparison -Convex Mirror Concave Mirror
Meaning It’s a mirror that has a reflecting surface away from the centre of curvature A concave mirror is one that has a reflecting surface towards the curvature’s centre
Type Diverging mirror Converging mirror
Centre of Curvature It lies behind the mirror It lies in front of the mirror
Image Virtual image forms Real or virtual image forms
Projection Images do not project on the screen because they are virtual Images project on screen because they are real
Uses We use them as rearview mirrors in cars and bikes We use them as reflectors in projectors, searchlights, shaving mirrors and more
View These cover a wider area of view These give a magnified image of objects
2) A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens. Due to the diverging rays, it is called a diverging lens.
3) The mirror implies a glossy surface at one end and produces an image of an object by reflection. A mirror follows the laws of reflection. The lens is a transparent thick material that is shaped in such a manner that it bends the light passing through it.
