1. 5 differences between concave and convex mirror.
2. 5 differences between concave lens and convex lens.
3. Difference between real and vortual image.
HAVE AN EXAM TOMORROW
Please answer it thoroughly.
Answers
1. A convex mirror has a reflecting surface that bulges outside while
a concave mirror, the reflecting surface that bulges inwards.
convex mirror = diverging mirror
concave mirror= converging mirror
convex mirror virtual image is formed
concave mirror real or virtual image is formed
covex mirror used as rear view mirror in cars nd bikes
concave mirror used as reflectors in projectors.
convex mirror reflecting surface is away from the center of curvature.
concave mirror reflecting surface is towards the center of curvature.
2. Convex lens refers to the lens which merges the light rays at a particular point, that travels through it.
Concave lens can be identified as the lens which disperses the light rays around, that hits the lenses
covex lens are Outward
concave lens are Inward
covex lens diverges
concave lens inverges
convex lens are thicker at the center, as compared to its edges.
concave lens are thinner at the center, as compared to its edges.
convex lens appear closer and larger.
concave lens appear smaller and farther.
3.real image can be taken on the screen.
virtual image cannot be taken on the screen
real images rays of light after reflection meets at a point
virtual images rays of light after reflection or refraction appears to meet at a point
real image is always inverted
virtual image are always irrect and laterally inverted.
thankyou
please mark me as a brainliest
nd follow meh!;)
hope it help
