1.	In case of superposition of waves (atx=0), y_(1)=4sin(1026pit) and y_(2)=2sin(1014pit) (a) the frequency of resulting wave is 510Hz (b) the amplitude of resulting wave varies at frequency 3Hz (c ) the frequency of beats is 6 per second (d) the ratio of maximum to minimum intensity is 9 The correct statements are
Answer» `a,d` `b,d` `a,c,d` all Solution :Number of beats equal to `n_(1)-n_(2)` , frequency of RESULTING wave equal to `(n_(1)+n_(2))/(2)`. RATIO of maximum and minimum INTENSITY is `((a_(1)+a_(2))/(a_(1)-a_(2)))^(2)`
