What is the cause of "Green house effect"? (a) Infrared rays (b) Ultraviolet rays (c) X-rays (d) Radio-waves

Statement-1 : Ultrasonics is the acoustic analogue of ultraviolet radiation Statement-2 : Ultraviolet rays do not produce visual sensations while ultrasonic waves are not heards by the human ear.

state True or False for the given statement a. X-ray are electromagnetic waves because these are producted by the deceleration of fast moving electron . b. X-ray are electromagnetic waves because these produce line spectrum. c. the cut-off wavelength depends on the target material . d. The intensity of K_(alpha) transition is more probable then of K_(beta) transition. e. Frequency of K_(alpha) radiation is more than that of K_(beta) .
