Reflection of light

Best regular reflection of light takes place when it strikes

• Smooth opaque surface

• Rough opaque surface

• Smooth transparent surface

• Smooth & silvered opaque surface

Light exhibits

• Ray nature only

• Wave nature only

• Dual nature ( ray & wave both )

• particle nature only

Laws of reflection of light are similar to the laws of reflection of sound

• True

• False

• a

• b

• c

• d

Law of reflection state that - The angle of incidence is .................. to the angle of reflection.

• equal
• double

In the image, all the rays appear to meet at F, What is F

• focal length

• focal point

• center of curvature

• reflection

Convex Mirrors produce...

• only virtual images
• virtual or real images
• only real images
• inverted images

If 'R' is radius of curvature and 'f' is focal length of a spherical mirror then the correct relation between the two is

• R = f

• R = f/2

• f = 2R

• f = R/2

Through which point on principal axis shall reflected ray pass in the following diagram of incident ray ?

• point F

• point C

• point P

• none of the above

A mirror always form diminished image irrespective of the position of the object in-front of it , then the mirror is :-

• Plane mirror

• concave mirror

• convex mirror

• not possible
