: the angle between a refracted ray and the normal drawn at the point of incidence to the interface at which refraction occurs.
Q. In which medium does light travel the fastest?
Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

Q. When light is entering a medium of lower refractive index then the light is?
This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it ‘bends’ more towards the normal line. The amount of bending depends on two things: Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.
Q. What is Snell’s law class 10 formula?
/frac{sin/;i}{sin/;r}=constant=/mu Where i is the angle of incidence and r is the angle of refraction. This constant value is called the refractive index of the second medium with respect to the first. Snell’s law formula is derived from Fermat’s principle.
Q. What is the 2nd law of reflection?
Second law of reflection: According to the second law, the angle of reflection is always equal to the angle of incidence. This ray of light will be reflected back along the same path. Objects and images. Anything which gives out light with off its own of reflected by it is called an object.
Q. What is the normal line in refraction?
The normal is a line perpendicular (forming a 90 degree angle) to the boundary between the two substances. The bending occurs because light travels more slowly in a denser medium. A demonstration of refraction can be conducted at home in a dark room.
Q. How does the type of medium affect refraction?
Refraction of Light: as it passes from more dense to less dense mediums. The bending of light as it passes from one medium to another is called refraction. The amount of refraction increases as the wavelength of light decreases.
Q. Does frequency of light change during refraction?
But the frequency remains the same. But wavelength and velocity are inversely proportional to each other. So, when the wavelength changes, the frequency should also change.
Q. What is the main cause of refraction?
The cause of the refraction of light is that light travels at different speeds in different media. This change in the speed of light when it moves from one medium to another causes it to bend. Refraction is caused due to the change in speed of light when it enters from one medium to another.
