List of top Physics Questions on Refraction of Light asked in AP EAPCET

When a light ray is incident on a small angle prism of material of refractive index 1.5, the angle of minimum deviation is $7^\circ$. If the prism is immersed in a liquid of refractive index 1.2, then the angle of minimum deviation is:
A vessel of depth \(x\) is half filled with oil of refractive index \(\mu_1\) and the other half is filled with water of refractive index \(\mu_2\). The apparent depth of the vessel when viewed from above is

A light ray incidents on a prism PQR ($PQ=QR$) and travels as shown in the figure. The minimum refractive index of the referred prism is:

A layer of oil floats on water. A ray of light strikes the oil-water interface at an angle of incidence \(30^\circ\). The refractive indices of oil and water are 1.5 and 1.3 respectively. The angle made by the ray in water is:
A light ray is incident from a medium of refractive index \(2\) into a medium of refractive index \(\sqrt{3}\). The critical angle is
A ray of light is incident at \(30^\circ\) from a medium of refractive index \(2\) into a medium of refractive index \(1\). Then the angle of refraction is:
A needle is lying at the bottom of a water tank of height \(12\,\text{cm}\). The apparent depth of the needle measured by a microscope is \(9\,\text{cm}\). If the water is replaced by a liquid of refractive index \(1.5\) of same height, the distance through which the microscope has to be moved to focus the needle again is
