Interactive Quiz: Reflection of Light

Question 1 of 10

According to the laws of reflection:

The incident ray, reflected ray, and normal all lie in different planes The angle of incidence is always greater than the angle of reflection The incident ray, reflected ray, and normal all lie in the same plane, and angle of incidence equals angle of reflection Light always reflects back along the incident path

The laws of reflection state that: (1) The incident ray, reflected ray, and normal all lie in the same plane. (2) The angle of incidence equals the angle of reflection (θ_i = θ_r).

Question 2 of 10

Which of the following are characteristics of images formed by plane mirrors?

Virtual image Magnified image Laterally inverted Image distance equals object distance

Images formed by plane mirrors are: (1) Virtual (cannot be projected on screen), (2) Upright, (3) Same size as object (not magnified), (4) Laterally inverted, (5) Image distance equals object distance.

Question 3 of 10

When two plane mirrors are placed parallel to each other, the number of images formed is:

One Two Three Infinite

When two plane mirrors are placed parallel to each other, infinite images are formed due to multiple reflections between the mirrors. In practice, the images become progressively dimmer and may not all be visible.

Question 4 of 10

Two plane mirrors are placed at right angles (90°) to each other. How many images of an object will be formed?

One Two Three Infinite

When two plane mirrors are placed at 90° to each other, three images are formed: (1) One in each mirror (direct reflections), and (2) One composite image formed by double reflection in both mirrors.

Question 5 of 10

Which of the following statements about concave mirrors are correct?

They are converging mirrors They always form virtual images They are used in shaving mirrors The focal length is half the radius of curvature (f = R/2)

Concave mirrors are converging mirrors that can form both real and virtual images depending on object position. They are used in shaving/makeup mirrors (when object is within focal length for magnified virtual image), headlights, telescopes, etc. The relation f = R/2 is fundamental for spherical mirrors.

Question 6 of 10

For a convex mirror, the image formed is always:

Real and inverted Virtual and erect Magnified Formed at the center of curvature

Convex mirrors always form virtual, erect, and diminished images regardless of the object's position. This makes them useful for applications requiring a wide field of view like rear-view mirrors in vehicles.

Question 7 of 10

In the mirror formula (1/f = 1/v + 1/u), which of the following is correct for a convex mirror?

f is positive f is negative v is always positive u is negative for real objects

In the sign convention for mirrors: (1) f is negative for convex mirrors (positive for concave), (2) v is negative for virtual images (positive for real images), (3) u is always negative for real objects (as object distance is measured against incident light direction).

Question 8 of 10

Where should an object be placed in front of a concave mirror to get an image that is real, inverted, and same size as the object?

At the focus At the center of curvature Between focus and center of curvature Between pole and focus

When an object is placed at the center of curvature (C) of a concave mirror, the image formed is: (1) Real, (2) Inverted, (3) Same size as the object, and (4) Located at C (image distance = object distance).

Question 9 of 10

Which of the following applications use convex mirrors?

Shaving mirrors Rear-view mirrors in vehicles Security mirrors in stores Astronomical telescopes

Convex mirrors are used where a wide field of view is needed: (1) Rear-view mirrors in vehicles, (2) Security/surveillance mirrors in stores, (3) Blind corner mirrors at intersections. Shaving mirrors use concave mirrors for magnification, and telescopes primarily use concave mirrors for light gathering.

Question 10 of 10

For a concave mirror, if the object is placed between the focus and the pole, the image formed will be:

Real and inverted Virtual and erect Diminished Formed at infinity

When an object is placed between the focus (F) and pole (P) of a concave mirror: (1) The image is virtual (cannot be projected on screen), (2) Erect (not inverted), (3) Magnified (larger than object), and (4) Formed behind the mirror.
