Question

It is very urgent so who will give this answer first I will mark u as brainlist

Write the important notes on concave and convex lenses and mirror.​

Answer 1

the important notes of concave and convex are :


A convex mirror is opaque whereas a convex lens is transparent.

A convex mirror causes reflection of light whereas a convex lens causes refraction of light.

A convex mirror forms only virtual, diminished and erect images for all positions of the object, whereas a convex lens can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object. 

Difference between concave mirror and concave lens

A concave mirror is opaque whereas a concave lens is transparent.

A concave mirror causes reflection of light whereas a concave lens causes refraction of light.

A concave mirror can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object whereas a concave lens forms only virtual, diminished and erect images for all positions of the object.  

Answer 2

concave lenses

1)make virtual and small images

2)make erect images

3)diverge parallel rays

convex lenses

1)converge parallel lines to focus

2)makes real image

3)makes inverted images
