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 else can I help you with?
Refraction can separate white light into what?
Refraction can separate white light into the spectrum of visible light from red to violet.
Does the angel of refraction depend on the wavelength?
Yes, the angel of refraction does depend on the wavelength of the light passing through a medium. This is known as dispersion, where different wavelengths of light are bent at different angles as they pass through a medium, causing them to separate.
How is refraction of light related to wave length of colors?
Refraction of light occurs when light waves enter a medium with a different refractive index, causing them to change speed and direction. The amount of refraction depends on the wavelength of the light, with shorter wavelengths (such as blue) being refracted more than longer wavelengths (such as red). This dispersion of colors in a prism is due to the varying refractive indices of different wavelengths of light.
What is the light refraction of sandstone?
Sandstone typically has a low refractive index due to its composition of mainly quartz and other minerals. Light passing through sandstone may experience minimal refraction or dispersion, depending on the specific mineral content and structure of the rock.

Why can we have refraction without dispersion but cannot have dispersion without refraction?
Refraction occurs when light travels through a medium with different optical density, causing a change in its speed and direction. This phenomenon can occur without dispersion, which specifically refers to the separation of light into different colors based on their wavelengths. Dispersion cannot occur without refraction because the bending of light during refraction is necessary for different colors to be refracted at different angles, leading to dispersion.
What are the seven properties of light?
refection refraction diffraction polarization interference dispersion photoelectric effect
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).
Refraction can separate white light into what?
Refraction can separate white light into the spectrum of visible light from red to violet.
The dependence of wave speed and index of refraction on wavelenght is called?
Dispersion.
What are the two phenomenon that suggest light propagates like wave?
Light exhibits refraction, diffraction, dispersion, and all the other properties of waves.
Light remains unchanged when it goes from matter?
Many phenomenons can occur: refraction, reflexion, absorption, dispersion, scattering, transmission.
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.
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.
How do rainbows get their color?
Rainbows get their colors from the reflection, refraction, and dispersion of light in water droplets. When sunlight passes through the droplets, the light is separated into its different colors, creating the rainbow effect we see in the sky.
Why dispersion occurs only during refraction not reflection?
Dispersion occurs during refraction because different wavelengths of light bend at different angles when they pass through a medium, leading to separation of colors. In reflection, light waves maintain their original composition as they bounce off a surface and do not bend or separate into different colors.
