Which statement descthe image shows the right-hand rule being used for a current-carrying wire. which statement describes what the hand shows? when the current flows down the wire, the magnetic field flows out on the left side of the wire and in on the right side of the wire. when the current flows up the wire, the magnetic field flows out on the left side of the wire and in on the right side of the wire. when the current flows down the wire, the magnetic field flows in on the left side of the wire and out on the right side of the wire. when the current flows up the wire, the magnetic field flows in on the left side of the wire and out on the right side of the wire. ribes what the hand shows?

i think it's 35 meters

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.
