Well in physics we know that when a wave crosses from one medium to another there is a change of speed. For all light rays, this change of speed is annotated by a change of direction. So given that air is less dense than water, then you would certainly expect the speed to decrease as it moves from the air into the water. And given that this change in speed is accompanied by a change in direction, the ray of light would then move towards the normal (an imaginary line that is perpendicular to the plane surface). To extend this further, if you would want to calculate the change in speed you can do this with the following equation.
To get the change in speed:
We know that the refractive index of air to water is |1.3|
so by means of the equation Speeda/Speedb=1.3
speed a is speed in air (3 X 10 to the power of 8) and speed b is the speed in water. So by substituting
3 X 10 to the power of 8/speed b=1.3
Speed b= 3 X 10 to the power of 8/1.3
By calculating you get the answer to be speed b= 2.3 X 10 to the power of 8 (speed of light in water)
What else can I help you with?
How will light be refracted if it passes from glass to water?
The light will be refracted towards the normal when it passes from glass to water, as water has a lower refractive index than glass. This means the light ray will bend towards the line that is perpendicular to the surface at the point of incidence.
Does clear glass refract light?
Clear glass does refract light when light passes from another medium like water to clear glass. But there is an exception. If the ray of light were to pass through water and hit the clear glass straight or at 90 Degrees to the surface, then clear glass does not refract the light.
What occurs when light passes from water into a flint glass?
When light passes from water into a flint glass, it undergoes refraction due to the change in optical density between the two mediums. The bending of light at the water-glass interface is caused by the difference in the speed of light in each medium, leading to a change in the light's direction.
Is the refractive index of water wrt glass less or more than 1?
The refractive index of water with respect to glass is more than 1. This means that light travels faster in water than in glass, causing the light to bend when it passes from glass to water.
What are three things refract light?
Glass: When light passes through glass, it refracts or bends. Water: Light refraction occurs as it moves from air into water or vice versa. Diamonds: The optical properties of diamonds cause them to refract light, resulting in their sparkling appearance.

What other objects can make refraction happen refraction happen?
Other objects that can make refraction happen include prisms, lenses, water droplets (creating a rainbow), and glass objects like windows or glasses. Refraction occurs when light passes from one medium to another and changes its speed, causing the light to bend.
What happens when light passes from three different mediums like water to glass and glass to air?
When light passes from water to glass, it changes speed and direction due to the difference in refractive indexes between the two mediums. When it passes from glass to air, the light again changes speed and direction, leading to refraction and possible reflection at the interface. The bending of light at each interface is determined by Snell's Law, which relates the angle of incidence and refractive indexes of the two mediums.
Why does the straw bend in the glass of water?
The bending of the straw in a glass of water is due to refraction of light. When light passes from air into water, it changes speed and direction, causing the apparent bending of the straw. This phenomenon is called refraction.
What medium does light pass through?
Light passes through many mediums, but some of the most important are: Water Glass Air & Vacuum And light passes through vacuums the fastest.
What happens when light passes through a glass of milk?
Light does not pass through a glass of milk. The glass is transparent, so the light will be refracted a bit when entering the glass, and again while leaving the glass, but milk itself is opaque. Light would be absorbed in the milk, and converted into heat.
What wave property can best explain the apparent bending of pencil when its dipped in a glass of water?
Refraction of light can best explain the apparent bending of a pencil when it is dipped in a glass of water. This is due to the change in speed of light as it passes from air into water, causing the light rays to bend.
Where can refraction be seen?
Refraction can be seen when light passes through different mediums such as air and water, causing the light rays to change direction. This phenomenon is visible in everyday situations, such as a straw appearing bent in a glass of water or when light bends as it passes through a prism.
