Relation between critical angles of water and glass is
A ray of light incident at angle of 40^(@) , on a glass slab , is deviated through 15^(@) , while passing through glass . What is the critical angle for the glass air surface ?
The ray of light is incident at an angle of 45^(@) on a glass surface. What will be the critical angle of the glass when placed in air if the light ray is deviated by 12^(@) ?
The critical angle of incidence in a glass slab placed in air is 45^@ . What will be be the critical angle when the glass slab is immersed in water of refractive index 1.33 ?
The critical angle for refraction from glass to air is 30° and that from water to air is 37° . Find the critical angle for refraction from glass to water
Refractive index of glass is 1.5. Find the speed of light in glass and critical angle for glass.
When a glass slab is placed on a cross made on a sheet, the cross appears to be raised by 1cm . The thickness of the glass is 3cm . The critical angle for glass is
