Light Reflection

The angle of incidence for a ray of light having zero reflection angle is :-------

• 0⁰

• 30⁰

• 45⁰

• 90⁰

An object is placed at a distance of 0.25 m

in front of a plane mirror. The distance between the object and image will be : -------

• 0.25 m

• 1.0 m

• 0.5 m

• 0.125 m

What is the size of the image formed when an object is kept at the focus in front of concave mirror?

• enlarged

• diminished

• highly enlarged

• highly diminished

According to laws of reflection,

• angle of incidence > angle of reflection

• angle of incidence < angle of reflection

• angle of incidence = angle of reflection

• both 1 and 2
