1.	Define that ligth, reflection and refraction in short anwer with example
Answer» Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the HUMAN eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometers, or 4.00 × 10⁻⁷ to 7.00 × 10⁻⁷ m, between the infrared and the ultraviolet. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. COMMON examples include the reflection of light, sound and water waves. In physics, refraction is the change in direction of a wave passing from one medium to another or from a GRADUAL change in the medium. Refraction of light is the most COMMONLY observed phenomenon, but other waves such as sound waves and water waves also EXPERIENCE refraction.
