G10-SCIENCE_LONG TEST#1-Q2

In the Law of Reflection, the incident ray, the reflected ray, and the normal line .

• are similar in position.

• lie on the same plane.

• lie on a perpendicular plane.

• may or may not lie on the same plane.

A ray of light is incident on a surface at 33o from the normal. What will be the angle of reflected ray from the normal?

An incident light travels on a path shown in

the picture. Which of the following paths is most

likely to be taken by the reflected light?

• a

• b

• c

• d

If you placed a number chart in front of a plane mirror, what numbers will you read properly in the mirror?

• 0, 1, 6, 8, and 9

• 0, 1, and 6

• 6 and 9

• 0 and 8

Answer explanation

The number 1 and 8 are the only two numbers with their identical mirror images.

Is it TRUE that (I) convex mirror always forms upright, reduced, and virtual images and (II) most department stores use concave mirrors because they give a wider range of view?

• I only

• II only

• Both I and II

• Neither I nor II

Answer explanation

Convenience stores use convex mirror to get a wider view of the store.

It is a position where an object should be placed when in front of a concave mirror so that it reflects the image with the same size as the object.

• At the focus

• At the center of the curvature

• Between the focus and the mirror

• Between the center of curvature and focus

What type of lens produces smaller and upright images?

What property of light is observable on lenses?

• Diffraction

• Interference

• Reflection

• Refraction

In the picture, which ray(s) will pass through the secondary focus after refraction?

• Ray 1

• Ray 2

• Ray 3

• Ray Gun

Where will the image form if the object is placed between

F and 2F as shown in the figure on the right?

• At F’

• At 2F’

• At infinity

• Beyond 2F’
