How does a prism split white light into a rainbow?
bearhunter [10]

Answer:

Explanation:

DECOMPOSITION OF LIGHT:

Descartes explained the formation of the rainbow and years later Newton studied the light and managed to break it down into the colors of its spectrum through a prism year 1666.

Newton knew very little about the nature of light, did not know that it was a wave and even less that it was an electromagnetic wave. He believed that it was formed by corpuscles, but he managed to break it down into its spectral colors. Today we know that light is both particle and wave.

Humans (and some animals) appreciate a wide range of colors that are usually due to the mixture of radiation (lights) of different wavelengths. The color of light with a single wavelength or a narrow band of them is known as pure color.

When the light passes through a glass prism, the different wavelengths that make up the light beam travel inside it at different speeds and curl differently when entering and leaving (double refraction when changing media) giving as result a beam diverted from the initial direction and with its separate components. Thus arises the solar spectrum.

Each of the different rays of light crosses the glass with different velocity and the average speed of light within the prism is less than in a vacuum. Light is a wave with an oscillating electric field that interferes with the charged particles in matter.

The visible radiations are between the following wavelengths: from 350 nm (nanometers) for violet to 750 nm for red.

\Parts of a device that use radio waves. On the left is a box labeled A. On the right is a box labeled B. There is a vector poin
Elodia [21]

The radio waves travels between the two boxes and they were travelling through air,

  • Box B captures, amplifies and demodulates radio waves.
  • Box A modulates, amplifies and send out radio waves.

<h3>What are radio waves?</h3>
  • Radio waves are the type of radiation from the electromagnetic spectrum.
  • The radio waves can be used in communication technologies like computer, phones, radios , etc..
  • Radio waves have lower frequencies but longer wavelength.
  • These devices will get signal and then it transmit as mechanical waves through sound.

In that way, the radio waves from box A to B through air, the box A will gets the signal, and then modulates, amplifies and then it send out radio waves. Through the air, Box B will captures, amplifies and demodulates radio waves.

A sled is initially given a shove up a frictionless 37.0 ∘ incline. It reaches a maximum vertical height 1.20 m higher than wher
labwork [276]

The initial speed of the sled at the given height is 4.85 m/s.

<h3>Initial speed of the sled</h3>

Apply the principle of conservation of energy;

K.E = P.E

¹/₂mv² = mgh

v² = 2gh

v = √2gh

where;

  • h is the vertical height reached
  • g is acceleration due to gravity

v = √(2 x 9.8 x 1.2)

v = 4.85 m/s

Thus, the initial speed of the sled at the given height is 4.85 m/s.
