Question

1. List any five properties of light​

Answer 1

$\Large{\underline{\underline{\sf \red{Answer:-}}}}$

The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature.

Answer 2

Answer:

Properties of Light

2. Properties of Light • • • • • • • • • Effects of Materials on Light Reflection Refraction Dispersion Total Internal Reflection Interference Diffraction Scattering of Light Polarization

3. Effects of Materials on Light Materials can be classified based on how it responds to light incident on them: 1. Opaque materials – absorb light; do not let light to pass through 2. Transparent materials – allow light to easily pass through them 3. Translucent materials – allow light to pass through but distorts the light during the passage

4. Reflection Light follows the Law of Reflection: “The angle of incidence is equal to the angle of reflection.” Light can bounce off materials in two ways: 1. Diffuse reflection – reflected rays go in different directions; happens in roughtextured or uneven surfaces 2. Regular/Specular reflection – reflected rays go in one directions; happens in smooth and shiny surfaces; image can be seen

5. Refraction Light bends/refracts when it changes speed. This usually happens when the light travels from one medium to the next. Simple rule of thumb in refraction: • If light slows down, it will refract towards the normal line. • If light speeds up, it will refract away from the normal line.
