Refraction
Lower Sec Science · Secondary 1 · Hard · Refraction
A ray of light travels from air into a glass block at an angle of incidence of 30° to the normal.
In glass, the ray bends towards the normal and makes an angle of refraction of 19°.
Which statement best explains this change in direction?
In glass, the ray bends towards the normal and makes an angle of refraction of 19°.
Which statement best explains this change in direction?
- Light slows down in glass, so it bends towards the normal.
- Light speeds up in glass, so it bends towards the normal.
- Light slows down in glass, so it bends away from the normal.
- Light travels at the same speed, so it does not bend at the boundary.
