Explanation:

Answer 2

Light is a type of electromagnetic energy that allows us to see or make things visible. Radiation that can be seen with the naked eye is also known as visible radiation. Photons are tiny packets of energy that are found in light.

Light has several important characteristics:

• The speed of light is constant.
• Sound travels at a quicker rate than light. 3 x 108 m/s is the speed at which light travels.
• Light is reflected.
• Because light is a transverse wave, it travels without the use of a medium.
• It is not necessary for light to move via a physical medium. It can, in other words, travel in a vacuum.
• The speed of light in a vacuum has been calculated to be 299, 792, 458 metres per second.
• When light travels from one medium to another, its wavelength () shifts.
• When light passes through a transparent substance, it experiences refraction (bending).
