Answer 1

1. What is the nature of light? Light is a transverse, electromagnetic wave that can be seen by humans. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of ight can be demonstrated through polarization In 1678, Christiaan Huyges 1629 1695) published Traité de la Lumiere, where he argued in favor of the wave nature of light. Huygens stated that an expanding sphere of light behaves as if each point on the wave front were a new source of radiation of the same frequency and phase. Thomas Young (1773 1829) and Augustin-Jean Fresnel (1788 1827) disproved Newton's corpuscular theory. Finally it has reflection, refraction, interference, diffraction, polarization and dual nature (wave and particle 2. Sate the law of reflection (both parts-angle and distance; in words and equation) 1. The incident ray, reflected ray and normal at the point of incidence lie on the same plane. 2. The angle which the incident ray makes with the normal (angle of incidence is equal to the angle which the reflected ray makes with the normal (angle of reflection). (iT) normal incident ray reflected ray mirror
