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?

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 is light refraction and dispersion demonstrated?
Light refraction is the bending of light as it passes from one medium to another, due to a change in its speed. Dispersion occurs when different wavelengths of light are refracted by varying amounts, leading to the separation of white light into its constituent colors, such as in a prism. This phenomenon can be observed when light enters a prism, resulting in a spectrum of colors ranging from red to violet. Together, refraction and dispersion illustrate how light interacts with materials to create visible effects.
What principle does a prism demonstrate that starts with a r?
A prism demonstrates the principle of refraction. Refraction occurs when light passes through the prism, bending as it moves from one medium (air) into another (the glass of the prism) due to a change in speed. This bending of light causes the different wavelengths (colors) to spread out, resulting in the dispersion of white light into its constituent colors.
Is the behaviors light exibits are reflection refraction diffraction polarization and dispersion?
Yes, the behaviors exhibited by light include reflection, refraction, diffraction, polarization, and dispersion. Reflection occurs when light bounces off a surface, while refraction is the bending of light as it passes through different media. Diffraction involves the bending of light around obstacles, polarization refers to the orientation of light waves in specific directions, and dispersion is the separation of light into its constituent colors, often seen in prisms. Each of these behaviors illustrates the complex nature of light as both a wave and a particle.
Refraction can separate white light into what?
Refraction can separate white light into the spectrum of visible light from red to violet.
What are the two phenomenon that suggest light propagates like wave?
Light exhibits refraction, diffraction, dispersion, and all the other properties of waves.
The dependence of wave speed and index of refraction on wavelenght is called?
Dispersion.
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.
