1. If a light ray go through a boundary of air and glass(i.e. angle of incidence is 90 degree), Is there any refraction or reflection?
2. If angle of incidence is 0 degree( the light ray is normal to a glass), Is there any reflection?
3. Suppose the situation is same as (2), but the light ray go from air to water. Is there any refraction or reflection?
