Which is the incident ray on the surface of separation CD? PO
The angle between the incident ray and the normal is called the angle
of incidence. If so, can you explain what is angle of refraction? vis the aoglen
refaction
Using a protractor measure the angle of incidence and the angle of
refraction.
Is the angle of refraction greater or lower than the angle of incidence
when it goes from air to glass? angle of incidenle is more, angle of trafora ellers
What about from glass to air? angkot refraction mone
Which is of greater optical density - air or glass? glass
While going from air to glass, the refracted ray deviates towards
the normal/ deviates away from the normal. towards the normal

Answer 1

Answer:

Bouncing off a boundary (choice b) is reflection. Refraction involves passing through a boundary (choice a) and changing speed (choice c); however, a light ray can exhibit both of these behaviors without undergoing refraction (for instance, if it approaches the boundary along the normal). Refraction of light must involve a change in direction; the path must be altered at the boundary.
