WebThe value of the critical angle for a given pair of media depends on the colour of light. ( Hint: Remember VIBGYOUR Violet has minimum i c whereas Red has maximum). (i) For red light, the critical angle will be greater than 45°. (ii) For blue light, the critical angle will be less than 45 °. Concept: Total Internal Reflection WebNov 29, 2024 · c = sin -1 (1/µ d) If the denser medium is glass, c = sin -1 (1/µ g) In general terms, we can write Critical Angle Formula as: θcric = sin−1 nr ni θ c r i c = sin − 1 n r n i. Example: A ray of light strikes from a medium with n = 1.67 on a surface of separation with the air with n = 1. Find the value of critical angle. myfeedback ibmWeb16. When one is exactly at the critical angle, the light behaves in a way that may be interpreted as "something in between" refraction and reflection: it continues in a direction that is tangent to the boundary of the mediums. When the angle is smaller than the critical angle, we get refraction. At the critical angle, θ2 of the refraction ... off the lot remix
