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
The light will bend as it passes through.
light rays bend away from normal as it passes from denser water to rarer air
That depends what it comes out of. If it passes into air from vacuum, thenits speed decreases. If it passes into air from water or jello, then its speedincreases.
The speed of the light decreases, and its wavelength increases by the same factor.
Air is a gas silly ;)
It gets faster. As a result, it also changes its direction.
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.
Yes
