EXPLANATION

Visible light is the light that we can see, and thus is the only light detectable by the human eye. White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers.

QUESTION

2. Bending of light

ANSWER

E. Refraction

EXPLANATION

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.

QUESTION

3. Exhibit the characteristics and properties of wave.

Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That's why light is called Electromagnetic Radiation. The shortest wavelengths of the spectrum are the ultraviolet, x-ray, and gamma radiation.

QUESTION

4. Special kind of refraction

ANSWER

B. Dispersion

EXPLANATION

Dispersion, in wave motion, any phenomenon associated with the propagation of individual waves at speeds that depend on their wavelengths. Dispersion is sometimes called the separation of light into colours, an effect more properly called angular dispersion.

QUESTION

5. It can separate white light into different colors

ANSWER

A. Prism

EXPLANATION

Prism, in optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.
