A common example of diffraction of light is looking at an object that is partially immersed in water, where the object appears to be in a different place. Sound diffraction is usually not visible, but it is audible through walls or other solid objects.Continue Reading
Diffraction of light is the easiest to recognize, since it takes only a glance. Looking at something beneath the surface of the water is one example. In spear fishing, the fish appears to be somewhere it is not due to how the water affects light. Water droplets also diffract light in the same way.
The diffraction of sound is more difficult to pinpoint, but is most noticeable when solid items, such as walls or columns, are between the listener and the source of the sound. Sound also diffracts when it passes through water in a similar fashion to light. The waves slow down when passing through water, distorting the end result.
A good way to visualize diffraction is to imagine ripples or waves in water. If the waves are moving in a uniform line and the middle of the line hits a pole or wall, the waves bend around the obstacle and their form is changed, just like sound and light waves.Learn more about Optics & Waves
A spectroscope relies on separating light into its component parts because of the information that can be obtained from examining the wider spectrum of colors that composes white light as it is reflected off an object. Such information can include elemental composition as well as how much of a particular element makes up the object that is being looked at.Full Answer >
Light is made up of billions of tiny particles known as photons, which travel from one place to another place in waves known as light waves. Visible light waves are the only electromagnetic waves that the human eye can see. These waves are visible as the seven colors of the rainbow known as red, orange, yellow, green, blue, indigo and violet.Full Answer >
The most commonly seen example of a convex mirror is the side view mirror on a car. Convex mirrors are seen in dome mirrors found in offices and stores for security and anti-theft purposes.Full Answer >
When light passes through a transparent medium such as water or glass, the electrons slow down, which causes the light to refract. As light enters the transparent medium, the wavelength colors bend at different angles to create a rainbow. .Full Answer >
