Answer 1

Answer:

(a) The color of scattered light depends on the size of the scattering particle. Very fine particles scatter short wavelengths such as blue and voilet lights. Large size particles scatter light of longer wavelengths.

(b) The basic cause of this observation is atmospheric refraction. As hot air is less denser than colder air surrounding it, it has a slightly lower refractive index. Since the physical condition of the retracting medium, in air is not stationary, the apparent position of an object, when seen through hot air fluctuates.

Answer 2

1)The scattering of light and the color of the scattered light depends upon the size of the particles. Smaller particles scatter the light of shorter wavelength, like blue and violet and larger particles scatter longer wavelength like, red and orange.

2)We observe random wavering or flickering of the objects near a fire on a very hot day due to atmospheric refraction. ... Refractive index of the hot air is slightly less than that of the cold air. Since, the density does not remain the same , the Apparent position of the object as seen through hot air ,fluctuates.
