A double convex lens of focal length '$$F$$' is cut into two equal parts along the vertical axis. The focal length of each part will be
The size of the real image produced by a convex lens of focal length $$F$$ is '$$m$$' times the size of the object. The image distance from the lens i...
The prism has refracting angle '$$\mathrm{A}$$'. The second refracting surface of the prism is silvered. Light ray falling on first refracting surface...
To get three images of a single object, the angle between the two plane mirrors should be
Two lenses of power $$-15 \mathrm{D}$$ and $$+5 \mathrm{D}$$ are in contact with each other. The focal length of the combination is
Which of the following is NOT involved in the formation of secondary rainbow?
A double convex air bubble in water behaves as
If a ray of light in denser medium strikes a rarer medium at angle of incidence $$i$$, the angles of reflection and refraction are $$r$$ and $$r^{\pri... A transparent glass cube of length$$24 \mathrm{~cm}$$has a small air bubble trapped inside. When seen normally through one surface from air outside,... The angle of prism is$$A$$and one of its refracting surface is silvered. Light rays falling at an angle of incidence '$$2 \mathrm{A}$$' on the first... The refractive index of glass is 1.5 and that of water is 1.33 . The critical angle for a ray of light going from glass to water is A convex lens is dipped in a liquid whose refractive index is equal to refractive index of lens material. Then its focal length will A ray of light is incident at an angle 'I' on one face of thin prism. The ray emerges normally from the other face. Refractive index of the glass pris... A glass cube of length$$24 \mathrm{~cm}$$has a small air bubble trapped inside. When viewed normally from one face it is$$10 \mathrm{~cm}$$below t... A particle executes linear S.H.M. The mean position of oscillation is at the principal axis of a convex lens of focal length$$8 \mathrm{~cm}$$. the m... A convex lens of focal length$$\mathrm{T}$$is used to form an image whose size is one fourth that of size of the object. Then the object distance is... Inside a vessel filled with liquid a converging lens is placed as shown in figure. The lens has focal length$$15 \mathrm{~cm}$$when in air and has r... A ray of light travels from a denser medium to a rarer medium. The reflected and the refracted rays are perpendicular to each other. If '$$r' and '\$...
