A2. The velocity of light is greatest in a vacuum. It will travel at a slower speed in a solid such as glass - (or indeed any transparent substance) and the various colours do not all travel at the same velocity. This underlies the dispersion of colours in a prism.
A1. Neither, light never slows down. Ever.
What else can I help you with?
Speed of light will be minimum when it passes through?
The speed of light is constant and does not change based on the material it passes through. However, when light enters a medium such as glass or water, its speed decreases due to interactions with the atoms in the material.
What do you call it when light the speed of light changes as it passes through different meduims?
Diffraction.
Is the speed of light in water should be more than the speed of light in a vacuum?
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
What percentage of the speed of light in vacuum is the speed of light in water?
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
What is it called when the speed and direction of light changes as it passes through different media?
its called refraction
Speed of light will be minimum when it passes through?
The speed of light is constant and does not change based on the material it passes through. However, when light enters a medium such as glass or water, its speed decreases due to interactions with the atoms in the material.
What happens when light passes through vacuum?
it travels at c (speed of light in a vacuum)
When is light bent as it passes through an object?
When the speed of light in the two media is not the same.
What do you call it when light the speed of light changes as it passes through different meduims?
Diffraction.
Which is the minimum speed of light passes through?
Zero (0) light cannot pass through opaque materials.
How does light passing through glass affect its speed and direction?
When light passes through glass, its speed decreases and it bends, or refracts, due to the change in the medium.
How do objects bend light?
Objects can bend light through a process called refraction, where light changes speed as it passes through different mediums. This change in speed causes the light to bend. Additionally, the shape and density of an object can also affect how light is bent as it passes through or around the object.
Why does light slow down when it passes through different mediums?
Light slows down when it passes through different mediums because it interacts with the atoms and molecules in the medium, causing it to change direction and speed. This interaction results in a decrease in the speed of light as it travels through the medium.
What happens to the speed of light when it passes through water?
It slows from c to c/n where n is the refractive index of water
Is the speed of light in water should be more than the speed of light in a vacuum?
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
Do windows refract light?
Yes, windows can refract light. When light passes through a window, the change in speed and direction of the light can cause it to bend or refract. This is why you might see rainbows or colors appear when light passes through a window.
What percentage of the speed of light in vacuum is the speed of light in water?
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
