As a ray of light travels from the air to water, refraction occurs. This is because the light has entered a medium where its speed is different. The light is bent towards the normal as the edge of the ray that first touches the water is slowed. Picture yourself driving a car when you drive through a puddle on the right edge of the road. The right tire enters the puddle and, since it can't travel as swiftly in water, it slows, causing the car to turn slightly to the right.
It's speed will increase. As a result, there will be refraction (the light will change direction).
It can be refracted, which would result in the electromagnetic spectrum being spread out.
It increases.
it slows down.
slowdown
When light passes from air into water, its velocity decreases due to the higher refractive index of water. This results in the light's wavelength also decreasing.
When light passes from air into water, it undergoes refraction, causing it to change direction. This is due to the change in speed of light as it moves from a less dense medium (air) to a denser medium (water). The light ray bends towards the normal (an imaginary line perpendicular to the surface) when entering the water.
It gets faster. As a result, it also changes its direction.
False. When light passes from water into air, it bends towards the normal.
The speed of light though substances is slower than the speed of light in a vacuum. As the light passes from air to water it slows and the ray's path is translated towards the normal to the air/water interface slightly.
The speed decreases.
When light goes from water to air, it undergoes refraction, causing it to change speed and direction. This change in speed and direction is due to the different optical densities of water and air. As a result, the light ray bends away from the normal line at the water-air boundary.
Yes
The speed of light slows in water.
