Why light passes undeviated falling straight on a refracting medium?

If by "straight on" you mean at 90 degrees to the surface of the medium, that is because light is only deviated if it makes an angle with the normal, which is an imaginary line perpendicular to the surface of the medium. If no angle is made between the normal line and the light ray, then no refraction occurs and the light passes through in a straight line.

What is 0 degree incidence?
when a ray of light falls normally ie. perpendicular to the refracting or reflecting ,the the angle of incidence is zero(angle of incidence is the angle between the incident ray and the normal at the point of incidence) A ray with 0 angle of incidence doesnot suffer any change on refraction and goes straight into the second medium.

What is a rarer medium?
If the light travels faster in the second medium, then this medium is called the rarer medium.
What is another word for the substance in which a wave travels?
A medium.
What is the difference between refract and reflect?
Reflection is where the light hits the surface and `bounces` back off the surface, while refraction is where the light enters the medium and changes direction according to the refractive index of the medium. The higher the refractive index, the more the light is refracted.
Why a light ray falling perpendicular on a medium does not reflect?
It DOES reflect. Straight back to where it came from.
What is refracting index of a medium?
Refractive index of the medium is defined as the ratio of the velocity of light in vacuum to that in the medium. No unit for refractive index.
What does refracting to light?
Any change in the refractive index of the medium through which the light is travelling causes refraction of light.
If light waves change speed as they pass from one medium into another at an angle the light will be?
Refracting
How does a CD rfract light?
Refraction is the bending of light through any medium. A CD uses refracting titanium foil.
Wh yis light refracted when it passes from air to water?
The density of the medium through which the light is passing, changes - refracting the light.
What are the ratings and certificates for Medium Straight - 1988?
Medium Straight - 1988 is rated/received certificates of: Iceland:12 West Germany:16
Easy hair cut for straight thin medium length hair?

What is 0 degree incidence?

What are some examples of a medium in science?
air,glass,and water,if the medium does not change it will travel in straight lines
What is terminal motion?
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
When does light travel in a straight line?
travels through a uniform medium
