A beam of light propagates through a medium 1 and falls onto another medium 2

A plastic hemisphere has a radius of curvature of 8cm and an index of refraction of 1.6 . On the axis halfway between the plane surface and the spherical one (4cm from each ) is a small object O. The distance between the two images when viewed along the axis from the two sides of [...]

A lens forms a real image of an object. The distance from the object to the lens is x cm and that from the lens to the image is y cm. The graph shows the variation of y with x. It can be deduced that the lens is A beam of light propagates through a [...]

Two thin lenses are placed 5cm apart along the same axis and illuminated with a beam of light parallel to that axis. The first lens in the path of the beam is a converging lens of focal length 10cm whereas the second is a diverging lens of focal length 5cm. If the second lens if [...]

A cube of side 2m is placed in front of a concave mirror of focal length 1m with its face A at a distance of 3m and face B at a distance of 5m form the mirror. The distance between the images of faces A and B and heights of images of A and B [...]

A beam of light propagates through a medium 1 and falls onto another medium 2, at an angle α 1 as shown in Fig. After that, it propagates in medium 2 at an angle α2 as shown. The light’s wavelength in medium 1 is λ1. What is the wavelength of light in medium 2? A [...]

A beam of light propagates through a medium 1 and falls onto another medium 2, at an angle alpha 1 as shown in figure. After that, it propagates in medium 2 at an angle alpha 2 as shown. A beam of light propagates through a medium 1 and falls onto another medium 2 at an [...]
