CGP EDU Academic Team · Accepted Answer

The correct answer is A. Matching Column I with Column II:(i) In refraction - In refraction, the frequency of the wave remains constant while the speed and wavelength change depending on the medium. Therefore, the correct match is: Answer: [C] frequency does not change.(ii) In reflection - In reflection, when a wave reflects off a medium, specifically from a denser to a rarer medium, there is no change in speed or wavelength. Thus, the correct match is:Answer: [A] Speed of wave does not change.(iii) In refraction from a rarer to a denser medium - When light moves from a rarer medium to a denser one, the wavelength decreases while the frequency remains unchanged. Thus, the correct match is:Answer: [B] wavelength must be decreased.(iv) In reflection from a denser medium - When a wave reflects off a denser medium, there is a phase change of π (which corresponds to a half-wavelength shift). Hence, the correct match is:Answer: [D] Phase change of π must take place.Final Matching:(i) - [C](ii) - [A](iii) - [B](iv) - [D]Summary: For the options provided: (i) [C], (ii) [A], (iii) [B], (iv) [D]. Therefore, the first correct answer matches with option A.
