A ray ACB is incident of a spherical mirror whose centre of curvature is C. In which direction will it reflect ?

A light ray I is incident on a plane mirror M .The mirror is rotated in the direction as shown in the figure by an arrow at frequency (9)/(pi) "rev"//"sec" ,The light reflected by the mirror is received on the wall W at a distance 10m from the axis of rotation .When the angle of incidence becomes 37^(@) find the speed of the spot (a point) on the wall?

The direction of ray of light incident on a concave mirror is shown by PQ while directions in which the ray would travel after reflection is shown by four rays marked 1, 2, 3 and 4 (See figure). Which of the four rays correctly shows the direction of reflected ray ?

A ray of light is incident on a concave mirror . It is parallel to the principal axis and its height from principal axis is equal to the focal length of the mirror. The ratio of the distance of point B to the distance of the focus from the centre of curvature is (AB is the reflected ray)

A slab of glass, of thickness 6 cm and refractive index mu =1.5 is placed in front of a concave mirror. If the radius of curvature of the mirror is 40 cm and the reflected image coincides with the object, then the distance of the object from the mirror is

A light ray is incident perpendicular to one face of a 90^@ prism and is totally internally reflected at the glass-air interface. If the angle of reflection is 45^@ , we conculde that for the refractive index n as

A ray is incident on a glass sphere as shown.The opposite surface of the sphere is partially silvered .If the net deviation of the ray transmitted at the partially silvered surface is 1//3^(rd) of the net deviation suffered by the ray reflected at the partially silvered surface(after emerging out of the sphere).Find the refractive index of the sphere.

A small object is placed 50 cm to the left of a thin convex lens of focal length 30 cm. A convex spherical mirror of radius of curvature 100 cm is placed to the right of the lens at a distance of 50 cm. The mirror is tilted such that the axis of the mirror is at an angle theta =30degree to the axis of the lens, as shown in the figure If the origin of the coordinate system is taken to be at the centre of the lens, the coordinates (in cm) of the point (x,y) at which the image is formed are

A ray of light travelling in the direction (1)/(2) (hati+sqrt3hatj) is incident on a plane mirror. After reflection, it travels along the direction (1)/(2) (hati-sqrt3hatj) . The angle of incidence is

A concave mirror is placed on a horizontal table, with its axis directed vertically upwards. Let O be the pole of the mirror and C its centre of curvature. A point object is placed at C. It has a real image, also located at C. If the mirror is now filled with water, the image will be.

A ray of light is incident on a thin film, As shown in figure, M and N two reflected rays while P and Q are two transmitted rays. Rays N and Q undergo a phase change of pi . Correct ordering of the refracting indices is
