Practice Questions for Ray Optics

An object is placed at a distance of 10 cm from a projector lens to obtain an image with a magnification of -60. At what distance should the screen be placed to receive the projected image?

A concave mirror forms a real image on a screen that is three times the size of the object. The object and screen are then moved until the image formed on the screen becomes six times the size of the object. If the shift of the screen is 39 cm, what is the focal length of the mirror?

A shaving mirror is constructed in such a way that a man at a distance of 30 cm from the mirror sees his virtual image magnified 1.33 times. What is the radius of curvature of the mirror?

According to the New Cartesian Sign Convention, the focal length of a concave mirror is:

In a plane mirror, a virtual image is always formed ______.

An object is placed in front of a concave mirror of radius of curvature 15 cm at two different positions: (a) 10 cm and (b) 5 cm. Determine the case in which the image formed is magnified, virtual, and erect.

A small candle of size 4.5 cm is placed 30 cm in front of a concave mirror of radius of curvature 42 cm. At what distance from the mirror should a screen be placed in order to obtain a sharp image?

A light ray falls on a glass surface of refractive index √3 at an angle of incidence of 60°. The angle between the refracted ray and the reflected ray would be:

When two plane mirrors are placed parallel to each other, how many reflected images of an object placed between them are formed?

The focal length f is related to the radius of curvature r of a spherical convex mirror by:

A magnifying glass is useful because it allows an object to be brought closer to the eye than the normal near point. This primarily results in:

Between the primary and secondary rainbows, there is a dark band known as Alexander's dark band. This phenomenon occurs because:

A rectangular block of glass ABCD has a refractive index of 1.6. A pin is placed midway on the face AB. When an observer attempts to view the pin directly through the adjacent perpendicular face AD, the pin shall:
