- This document discusses key properties of light including reflection, refraction, diffraction, and interference. Reflection occurs when light bounces off a surface, following the law that the angle of incidence equals the angle of reflection. Refraction is the bending of light when passing from one medium to another at different speeds.

Aug 19, 2011 · Properties of light. Light travels in straight lines and very fast, faster than sound. We see objects because they reflect light into our eyes, while shadows are formed when light is blocked. There are two main types of reflection - specular reflection off smooth surfaces like mirrors, and diffuse reflection off rough surfaces.

Apr 21, 2021 · It describes transparent, translucent, and opaque objects and defines shadows. It explains the laws of reflection and types of reflection and mirrors. It provides details about the parts of the eye like the cornea, iris, pupil, retina, lens, and optic nerve and how light enters and is focused in the eye.
Jan 12, 2022 · Reflection And Its Laws • When light is incident on a certain surface, it either gets reflected or bounces back. Such surfaces are well polished and act like a mirror. The phenomenon of light bouncing off surfaces is called reflection.

Describe how the intensity of light changes with. distance from the source. 3. Physics terms. light rays. reflection. emission. refraction. dispersion. electromagnetic radiation. 4. Equations.
Light has characteristics of intensity, color, and wavelength that determine how we perceive different objects and colors. Light comes from various sources both natural and man-made. It travels in straight lines and can be reflected, refracted, or absorbed.
• Light is a naturally occurring substance that enhances vision and makes objects visible. Sun is the natural source of light. Travelling Of Light In A Straight Line: The path of light gets blocked when an object covers the source of light. This is illustrated by trying to see the flame of a candle using a straight pipe and then with a bent pipe.

Ans. Light has several properties, including wavelength, frequency, amplitude, and polarization. The wavelength of light determines its color, while the frequency determines its energy. Amplitude refers to the intensity of the light, and polarization describes the orientation of the electric field. 3.
