The angle between an incident ray and the plane mirror is 30°. The total angle between the incident ray and reflected ray will be:

30° 60° 90° 120°

When an object is placed between the pole and focus of a concave mirror the image formed is:

Behind the mirror Virtual and erect and, Larger than the object or magnified All the above

Anjali is writing some statements, choose the correct statement and help him:

The point at which the incident ray falls on the mirror is called the point of incidence. The angle of incidence is the angle made by the incident ray with the normal at the point of incidence. The normal is a line at right angle to the mirror surface at the point of incidence. All the above

Read the following sentences carefully, and choose the incorrect one about light:

The process of sending back the light rays which fall on the surface of an object, is called reflection of light. An aluminum metal is one of the worst reflectors of light. The objects having polished surface reflect more light than objects having unpolished, dull surface. The reflection of light in a plane mirror takes place at the silver surface in it.

Magnification produced by a rear view mirror fitted in vehicles

is less than one is more than one is equal to one can be more than or less than one depending upon the position of the object in front of it.

Which of the following statements is true?

A convex lens has 4 dioptre power having a focal length 0.25 m A convex lens has -4 dioptre power having a focal length 0.25 m A concave lens has 4 dioptre power having a focal length 0.25 m A concave lens has -4 dioptre power having a focal length 0.25 m.

Under which of the following conditions a concave mirror can form an image larger than the actual object?

When the object is kept at a distance equal to its radius of curvature When object is kept at a distance less than its focal length When object is placed between the focus and centre of curvature When object is kept at a distance greater than its radius of curvature

A 10 mm long awl pin is placed vertically in front of a concave mirror. A 5 mm long image of the awl pin is formed at 30 cm in front of the mirror. The focal length of this mirror is

-30 cm -20 cm -40cm -60 cm

These days New Cartesian Sign convention is used for measuring the various distance in the ray diagrams of spherical mirror.

Choose the correct statements:

Distance measure downward and perpendicular to the principal axis are taken as negative.

Distance measured upward and perpendicular to the principal axis are taken as positive.

Distances measured against the direction of incident light are taken as negative.

All the above.

A light ray enters from medium A to medium B as shown in figure. The refractive index of medium B relative to A will be

greater than unity

less than unity

equal to unity

zero

The image formed by a convex lens can be

Virtual and magnified

Virtual and diminished

Virtual and of same size

Virtual image is not formed

If an incident ray passes through the focus, the reflected ray will

Pass through the pole

Be parallel to the principal axis

Retrace its path

Pass through the centre of curvature

When the object is placed between f and 2f of a convex lens, the image formed is

At f

At 2f

Beyond 2f

Between O and f

A ray of light is travelling from a rarer medium to a denser medium. While entering the denser medium at the point of incidence, it

Goes straight into the second medium

Bends towards the normal

Bends away from the normal

Does not enter at all

A full length image of a distant tall building can definitely be seen by using

A concave mirror

A convex mirror

A plane mirror

Both concave as well as plane mirror
