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
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.
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).
