What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10²⁵ hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.
How the light affect the color we see?
All of the colors we see are a byproduct of spectrum light, as it is reflected off or absorbed into an object. An object that reflects back all of the rays of light will appear white; an object that absorbs all of the rays, black. All of the millions of other colors are produced by a combination of light rays being absorbed and reflected.

Explanation:
It is given that,
Height above which the stone was thrown, h = 10 m
Initial velocity of the stone, u = 8 m/s
Angle above the horizontal,
The horizontal component of velocity is,
The vertical component of velocity is,
Let t is the time of flight in vertical motion. The second equation of motion is :
t = 0.34 seconds
Let s is the range of the stone. It can be calculated as :
s = 2.46 meters
So, the range of the stone is 2.46 meters. Hence, this is the required solution.
