Using a glass of water, you can demonstrate both principles.
1. Place a spoon halfway submerged in the water. Note that when you look through the side surface of the water, the spoon appears to be bent, or disjointed, at the surface of the water. This is due to refraction of the light passing through the water to your eye.
2. Place the glass of water several inches in front of a white background. place a bright a light source in front of the glass/background. Note that the area behind the glass is not as brightly lit as the rest of the background. This is because the light passing the water is dispersed and fewer Photons/Area are hitting the background. That is to say, there is less light density behind the glass where the light was dispersed. Note that the opposite effect (brighter behind the glass) can occur, if the glass of water acts as a "Focusing lens" due to its shape!

What are the effects of refraction of light?
The effects of the wave nature of light include the reflection, refraction, dispersion, and diffraction of light, and its behavior during constructive and destructive interference. Everyday examples include: -- Mirrors, which would not work without reflection. -- Eyeglasses and the human eye, which would not work without refraction. -- Satellite dishes, which would not work without constructive interference.
When convexity of the lens is increased and light refraction does what?
The light refraction is decreased.
Is a light bulb an example of reflection or refraction?
It is refraction
How are refraction and dispersion demonstrate light?
They don't demonstrate light; they assume that you have light in the first place.
What is the difference between refraction and dispersion?
refraction is when light bends because of the change in desity, dispersion is white light that splits in a prism inot the colours of the spectrum (red, yellow, orange, green, blue, indigo and violet) so refraction is light changing direction and dispersion is white light splitting inot the colours of the spectrum (red, yellow, orange, green, blue, indigo and violet).
What are the seven properties of light?
refection refraction diffraction polarization interference dispersion photoelectric effect
How will violet light react in the process of dispersion?
Violet light has a higher index of refraction than red or blue because it is a higher frequency wave. Violet light will have the largest angle of deviation during the process of dispersion.
What is the term for light energy that appears violet to red?
Its NT light energy it is the dispersion or splitting of light due 2 refraction. It is called 'spectrum' of light.
What are the two phenomenon that suggest light propagates like wave?
Light exhibits refraction, diffraction, dispersion, and all the other properties of waves.
Splitting white light is called what?
All the colours of light travel at different wavelengths.The length of the wavelengths depends on the amount of energy that the colour has. For example, red light has the longest wavelength, thus having the lowest energy. When the wavelengths of the colours change, due to a less or more dense atmosphere, the colours split. This is called Dispersion (the splitting of white light).
Light remains unchanged when it goes from matter?
Many phenomenons can occur: refraction, reflexion, absorption, dispersion, scattering, transmission.
How can white light be separated into the colored lights of which it is composed?
White light is a combination of seven fundamental colors namely: red, orange, yellow, green, blue, indigo, and violet. When white light hits a barrier, it is reflected, refracted, or absorbed. In refraction, there is a great possibility that this light will also undergo dispersion. Dispersion is the breaking of white light into all the colors of the visible spectrum.
Will dispersion occur if a polychromatic ray of light enters a prism at an angle of incidence of 90 degree from air to denser medium?
Dispersion will occur, in the sense that the phase velocity of the different wavelengths will be different. What you may be asking is whether refraction (a change in the direction of the light) will occur. Refraction will only be visible if the light impacts at an oblique angle, not 90 degrees.
What is the difference between diffraction and dispersion?
Diffraction = The amount of light passing through a photographic lens being adjusted by a diaphragm. Dispersion = The splitting of light of different colors due to the different indices of refraction at different wavelengths when the light enters a lens or prism.
What are the two ways that light is manipulated?
Reflection and refraction. (Another is absorption.) (Another of the two is dispersion and interference.) (And another one is diffraction.)
