Q

of light occurs when light strikes a material, and the energy that it carries is absorbed by the atoms of the material and is converted into thermal energy.

14
Q

it is the separation of visible light into its different colors. Upon passage through the prism, the white light is separated into its component colors - red, orange,
yellow, green, blue and violet.

16
Q

What are the two types of scattering?

A

Rayleigh and Mie scattering

17
Q

happens when the size of the scatterer is smaller than the
wavelength of light being scattered.

A

Rayleigh scattering

18
Q

occurs when light hits a water drop, aerosol, or other particle in the atmosphere that are large enough to scatter all the wavelengths of light.

A

Mie scattering

19
Q

is the slight bending of light around barriers. For this behavior of light to be noticeable, the wavelength of light must be approximately the same or bigger than the slit or the opening of the barriers.

A

Diffraction

20
Q

it occurs when two waves meet while traveling through the same
medium and this behavior of light occurs.

A

Interference

21
Q

Interference can be?

A

Constructive and destructive

22
Q

the interference of two or more waves of equal frequency and phase, resulting in their mutual reinforcement and producing a single amplitude equal to the sum of the amplitudes of the individual waves.

A

Constructive interference

23
Q

the interference of two waves of equal frequency and opposite phase, resulting in their cancellation where the negative displacement of one always coincides with the positive displacement of the other.

A

Destructive interference

24
Q

governed by the behavior and properties of light

A

Optical phenomena

25
Q

What are the following Optical Phenomena?

A

Mirage, Haloes, Sun dogs, Rainbow

26
Q

it is an optical illusion caused by atmospheric conditions, especially the appearance of a sheet of water in a desert or on a hot road caused by the refraction of
light from the sky by heated air.

A

Mirage

27
Q

can be formed around the moon, sun, or any celestial light source when there is enough elevation for cirrus clouds.

A

Haloes

28
Q

patches of light that sometimes appear beside the sun

A

Sun dogs

29
Q

a spectrum of light appearing in the sky

A

Rainbow

30
Q

Reflection, refraction, absorption, and dispersion can be explained by?

A

Wave and Particle Theory

31
Q

scattering, diffraction, and interference can be explained by?

A

Wave theory

32
Q

the photoelectric effect can only be explained by?

A

Particle theory
