The first law of reflection states that...

• The bigger the mirror, the smaller the image.

• The angle of Reflected ray and Image are bigger.

• The angle of Incidence ray and Reflected ray are always equal.

• The Image formed is always smaller than the object.

Concave lens is known as _______ while convex lens is also known as ________

• Refractive | Reflective

• Diverging | Converging

• Reflective | Refractive

  Plane Mirror - Bigger Image

  Convex - Smaller Image

• Plane Mirror - Same size of Image

  Concave -

  Smaller Image

  Convex - Bigger Image

• Plane Mirror - Same size of Image

  Concave -

  Bigger Image

  Convex - Smaller Image

• Concave -

  Bigger Image

  Convex - Smaller Image

If the angle of incident rays on a plane mirror is 90°, what would be the angle of the reflected ray?

• 90, since plane mirror is aligned in the normal line.

• 90, since it follows the first law of reflection.

• 45, because the size of the image is smaller and halved.

• 180, because there are 2 types of ray, multiply it by 2.

A mirror _____ while a lens _______

• Absorbs | Reflect

• Reflects | Refracts

• Reflect | Diffuse

• None of the above
