Critical angle diagram
WebRay diagrams explain reflection in a plane mirror. Beyond a critical angle all waves are totally internally reflected. Optical fibres use total internal reflection to carry light and information. WebThe angle of incidence is now less than the critical angle and the light refracts away from the normal into the air. You may be expected to complete a diagram similar to the one above in an exam.

Critical Angle: There are both Compression and Shear wave in the second material At the FIRST CRITICAL ANGLE Compression wave refracted at 90 Shear wave at 33 degrees in the material. 2nd. 90Beyond the 2nd. Critical Angle: All waves are reflected out of the material. NO wave in the material. S C. Between the 1st. And 2nd. WebThe largest possible angle of incidence which still results in a refracted ray is called the critical angle; in this case the refracted ray travels along the boundary between the two media. Refraction of light at the interface between two media. For example, consider a ray of light moving from water to air with an angle of incidence of 50°.
