Assertion : The focal length of lens does not change when red light is replaced by blue light. Reason : The focal length of lens does not depends on colour of light used.
Assertion : The images formed by total internal reflections are much brighter than those formed by mirrors or lenses. Reason : There is no loss of intensity in total internal reflection.
Assertion : Within a glass slab, a double convex air bubble is formed. This air bubble behaves like a converging lens. Reason : Refractive index of air is more than the refractive index of glass.
Assertion : A piece of red glass is heated till it glows in dark. The colour of glowing glass would be orange. Reason : Red and orange is complementary colours.
Assertion : We cannot produce a real image by plane or convex mirrors under any circumstances. Reason : The focal length of a convex mirror is always taken as positive.
 Assertion : Critical angle of light passing from glass to air is minimum for violet colour. Reason : The wavelength of blue light is greater than the light of other colours.
 Assertion : Just before setting, the sun may appear to be elliptical. This happens due to refraction. Reason : Refraction of light ray through the atmosphere may cause different magnification in mutually perpendicular directions.
 Assertion : The size of the mirror affect the nature of the image. Reason : Small mirrors always forms a virtual image.
Assertion : The mirrors used in search lights are parabolic and not concave spherical. Reason : In a concave spherical mirror the image formed is always virtual.
Assertion : When an object is placed between two plane parallel mirrors, then all the images found are of equal intensity. Reason : In case of plane parallel mirrors, only two images are possible.
