Which of the following describes reflection?

• Reflection is a bouncing off of light rays when it hits the surface like a plane mirror.

• Reflection is the bending of light rays when it hits the surface like a plane mirror.

• Reflection is a bouncing off of light rays when it hits the surface like a lens.

• Reflection is the bending of light rays when it hits the surface like a lens.

Which of the following examples shows reflection of light on smooth surfaces?

• Mayon Volcano and it’s reflection on calm water

• Taal Volcano and it’s reflection on wavy water

• A mountain and it’s reflection on wavy water.

• A boat and it’s reflection on wavy water.

A light ray, traveling parallel to a concave mirror’s axis, strikes the mirror’s surface. The reflected ray ____________.

• Passes through the mirror’s focal point

• Again, travel parallel to a concave mirror’s axis

• Travels at right angles to the mirror’s axis

• Passes through the mirror’s center of curvature

Where should an object be placed in front of a concave mirror so that the image will have the same size as the object?

• At the focus

• At the center of curvature

• Between focus and the vertex

• Between focus and the center of curvature

What kind of mirror is used by Department store to give a wider area and smaller image of the shopper/buyers?

• Plane mirror

• Convex mirror

• Concave mirror

• All the kinds of Mirror

Which of the following is TRUE about Law of Reflection?

• Angle of incidence is not equal to angle of reflection.

• Angle of incidence is equal to the angle of refraction.

• Angle of incidence is equal to the angle of reflection.

• Angle of incidence is equal to both angle of reflection and refraction.

It is a curved mirror in which the reflective surface bulges away from the light source.

• Concave Mirror

• Convex Mirror

• Plane Mirror

• Convex lens

Why it is that Concave mirror is also known as Converging Mirror?

• Because the parallel incident rays converge at a focal point before reflection

• Because the parallel incident rays converge at a focal point after reflection

• Because the parallel incident rays diverge at a focal point before reflection

• Because the parallel incident rays diverge at a focal point after reflection

Which of the following is a curved mirror in which the reflective surface bulges towards the light source?

• Concave Mirror

• Convex Mirror

• Plain Mirror

• Concave lens

Which of the following best describes the image formed by a concave mirror when the object is located somewhere between the focal point (F) and the center of curvature (C) of the mirror?

• Virtual, upright, and enlarged

• Real, inverted, and reduced

• Virtual, upright, and reduced

• Real, inverted and enlarged
