When a ray of light passes from one medium to another (rarer to denser or denser to rarer), which of the following phenomenon of light is observed?
Choose the correct relation for a combination of two prisms to be achromatic. (Where for the first prism: μv = refractive index of the medium in violet light, μr = refractive index of the medium in red light A = angle of the prism; For the second prism: μ′v = refractive index of the medium in violet light, μ′r = refractive index of the medium in red light, A’ = angle of prism.)
Consider the following statements. i) For a perfect reflection, the angle of incidence will be equal to the angle of reflection. ii) The critical angle is the angle of incidence in the denser medium for which the angle of refraction in the rarer medium is 90°. Which of the above statements are true?
A light ray travelling from denser to rarer medium at an angle of incidence more than critical angle of concerned media pair suffers.
Assertion (A): Small glass beads fixed on traffic signals glow brightly when light falls upon them.
Reason (R): Light is totally reflected when the angle of incidence exceeds a certain critical value and light travelling in a denser medium is reflected from a rarer medium.

Read the following information carefully and answer the questions that follow: Seven persons Tina, Vini, Yasir, Rishi, Sanya, Pankaj and Urmila live on the separate floors of a 7- floor building. Ground floor is number one; second floor is number two and so on. Each of them goes to a city viz. Paris, Istanbul, Shanghai, Durban, London, Madrid and Dubai but not necessarily in the same order. Only three people live above the floor on which Sanya lives. Only one person lives between Sanya and the one who goes to Paris. Vini lives just below the person who goes to Madrid. Only three people live between the one who goes to Paris and London. The person who goes to Madrid lives on an even numbered floor. Urmila lives just above Rishi. Urmila does not go to London. Only two persons live between Pankaj and the one who goes to Durban. Pankaj lives above the person who goes to Durban. Yasir does not go to Istanbul. Tina does not live just above or just below Sanya. The one who goes to Shanghai does not live just above or just below Pankaj. Who among the following lives on floornumber 7?
