WebPredictions based on light as a wave To explain the photoelectric effect, 19th-century physicists theorized that the oscillating electric field of the incoming light wave was … WebLight theory in the 19th century and beyond. In the face of this compelling evidence, nineteenth-century scientists had to concede that light was a wave. This happened slowly, though, hampered by Newton's reputation …

Light - Young’s double-slit experiment Britannica

WebLight rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray.

Q.2 Explain the statement that one’s eyes could not detect faint starlight if light were not particle-like. Q.3 How can a … WebNewton has given the theory that light is made of tiny particles. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of waves vibrating up and down perpendicular to the direction of light, and therefore formulated a way of visualizing wave propagation. This known as 'Huygens' Principle'. Video Explanation fried insects
