The difference between reflection and total internal reflection is that (a) the laws of reflection hold true for reflection

(d) all mirrors irrespective of their shape

Answer: Regular reflection  Diffused reflection 1 When all the parallel rays reflected from a plane surface are parallel, the reflection is known as regular reflection When all the parallel rays reflected from a plane surface...

(i) The laws allowing the British Government to restrict the import of corn is known as the "Corn Laws".  (ii) These laws were abolished because the industrialists and urban dwellers were...

(b) light goes from optically denser medium to rarer medium EXPLANATION:  When the light goes from a denser medium to lighter medium, it goes away from the normal. When the angle of...

(b) According to Snell’s Law,  sin i/ sin r =μ 2/μ 1 = where r = 90º for particular incidence angle called critical angle. When the incidence angle is equal to or greater than...

(a) The basic principle of communication in fibre optics is based on the phenomenon of total internal reflection.

(b) Difference between apparent and real depth of a pond is due to the refraction of light, not due to the total internal reflection. Other three phenomena are due to...

(a) The apparent flattening (oval shape) of the sun at sunset and sunrise is due to refraction

Conditions for total internal reflection are:  (i) Light must travel from denser to rarer medium.  (ii) Angle of incidence must be greater than critical angle (C). 

(a) An optical fibre is a thin, flexible, transparent fibre that acts as a waveguide or "light pipe" to transmit light between the two ends of the fibre. An optical...
