Answer: Magnetic Fields
Explanation: A Compass works by detecting the earth's magnetic fields. The earth has a iron core that is part liquid and part solid crystal due to gravitational pressure.
A wave is a disturbance that propagates, or moves from the place it was created. The simplest waves repeat themselves for several cycles and are associated with simple harmonic motion. Let us start by considering the simplified water wave in Figure 2. The wave is an up and down disturbance of the water surface. It causes a sea gull to move up and down in simple harmonic motion as the wave crests and troughs (peaks and valleys) pass under the bird. The time for one complete up and down motion is the wave’s period T. The wave’s frequency is
f
=

, as usual. The wave itself moves to the right in Figure 2. This movement of the wave is actually the disturbance moving to the right, not the water itself (or the bird would move to the right). We define wave velocity vw to be the speed at which the disturbance moves. Wave velocity is sometimes also called the propagation velocity or propagation speed, because the disturbance propagates from one location to another.
In dispersion Phenomenon the bending of light depends on the formula
![\delta = (\mu - 1)A](https://tex.z-dn.net/?f=%5Cdelta%20%3D%20%28%5Cmu%20-%201%29A)
here A is angle of prism
![\mu = refractive :\index](https://tex.z-dn.net/?f=%5Cmu%20%3D%20refractive%20%3A%5Cindex)
now here we know that value of refractive index will inversely depends on the wavelength of light
so here we will have maximum value of refractive index for violet light as we can see that its wavelength is minimum.
Since its refractive index is maximum so it will bend by maximum angle
so here correct answer will be
<em>Violet light will bend a lot.</em>
