The law of refraction is a general result of plane waves traveling from one medium to another.
Consider light. The speed of light in water is LESS than its speed in air, and it bends toward the normal (refracts). The speed of sound, however, is GREATER in water than it is in air, thus its "index of refraction" is less than one (i.e. sound bends away from the normal when traveling from air to water).

Why do light ray bend toward the normal when it passes air into water?
Light rays bend towards the normal when passing from air into water due to the change in speed of light between the two mediums. Light travels slower in water than in air because water has a higher refractive index than air, causing the light to refract towards the normal.
Does the refracted ray bend towards the normal in water or vegetbale oil?
In water, the refracted ray will bend towards the normal, while in vegetable oil, the refracted ray will also bend towards the normal, but to a greater degree compared to water.
Does light bend toward or away from the normal when it goes air into water?
Light bends towards the normal when it goes from air into water due to the increase in optical density of the medium, leading to a decrease in speed of light and hence bending towards the normal.
What Critical angle of light passing from glass to water is minimum from?
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.
When light passes from water into air the light bends away from the normal true or false?
False. When light passes from water into air, it bends towards the normal.
Why do light ray bend toward the normal when it passes air into water?
Light rays bend towards the normal when passing from air into water due to the change in speed of light between the two mediums. Light travels slower in water than in air because water has a higher refractive index than air, causing the light to refract towards the normal.
Does sound like light in passing from water to air?
Yes, the sound like the light is refracted and distorted. just like the broken spoon in a glass of water, sound waves under water are broken. Sound traveling from the air to the water are bent and scrambled, but lets say that the spoon was completely in the water, then it appear perfectly normal. so if the sound originated from the water then it would remain undistorted.
Does the refracted ray bend towards the normal in water or vegetbale oil?
In water, the refracted ray will bend towards the normal, while in vegetable oil, the refracted ray will also bend towards the normal, but to a greater degree compared to water.
Does light bend toward or away from the normal when it goes air into water?
Light bends towards the normal when it goes from air into water due to the increase in optical density of the medium, leading to a decrease in speed of light and hence bending towards the normal.
What method is used to keep sharks away?
passing strong sound vibrations through water.
What Critical angle of light passing from glass to water is minimum from?
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.
When light passes from water into air the light bends away from the normal true or false?
False. When light passes from water into air, it bends towards the normal.
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.
What is the light ray when it enter or exits a water air at an angle of 15 degrees with the normal?
When light enters or exits water into air at an angle of 15 degrees with the normal, the light ray will refract, or bend, away from the normal. This is because water is optically denser than air, causing the light to bend towards the less dense medium.
A ray of light traveling from air to water will bend which direction?
The ray will bend towards the normal.
What is the value of velocity of ultrasonic sound in water?
It should be about the same as the speed of normal sound. The speed of sound varies a bit, depending on the frequency, but usually that is not much.
Why if you equals 0 refractiondoes not takes place?
Because from air to water the item will go towards the normal and in water to air the item will gi away from the normal. So if it is already directly along the normal then it wont be refracted.
