When using the magnification equation, a value greater than 1 as the solution for m indicates that the image is

Larger than the object

Explanation:

The magnification of a lens/mirror is given by the equation:

where

is the size of the image

is the size of the object

from the formula, we see that if M is greater than 1, it means that

and so, it means that the image is larger than the object.

The negative sign simply tells if the image is upright or inverted: when M is positive, the image is upright, when M is negative, the image is inverted.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
