# Reflection and Refraction

Welcome to your Reflection class 10

Which one is correct related to the laws of reflection of light?

laws of reflection are applicable to

A number of rays parallel to the principal axis are falling on a concave mirror. After reflection they are all meeting/intersecting at a point on the principal axis of the mirror. This point is called the

The distance between the pole and the principal focus of a spherical mirror is called the

Is there a relationship between the radius of curvature R, and focal length f, of a spherical mirror

A ray parallel to the principal axis, after reflection, will pass through the

A ray passing through the principal focus of a concave mirror or a ray which is directed towards the principal focus of a convex mirror, after reflection

A ray passing through the centre of curvature of a concave mirror or directed in the direction of the centre of curvature of a convex mirror, after reflection

If the position of object is in Between P and F then the nature of image will be

In case of Concave mirror where should be the object placed to get a virtual and erect image of the object

at what location in case of concave mirror, both size of the object and size of the image are same

In case of convex mirror the size of the image is always

Which one is used as rear-view (wing) mirrors in vehicles.

The radius of curvature of a spherical mirror is 20 cm. What is its focal length?

which one is correct for mirror formula

A concave mirror produces three times magnified (enlarged) real image of object placed at 10 cm in front of it. Where is the image located?

A spherical mirror and a thin spherical lens have each a focal length of –15 cm. The mirror and the lens are likely to be

No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be

An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position of the image.

The magnification produced by a plane mirror is +1. What does this mean?
