The following items consist of two statements, one labeled as “Assertion (A)” and the other labeled as the “Reason (R)”. You are to examine the two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly. Assertion (A): In a magnetron, each cavity with its input gap acts as an open circuit transmission line of length half wavelength long. Reason (R): In magnetrons, the usual mode employed is the ‘π’ mode, where the phase change between the adjacent cavities is π radians.
