Homework Statement
2. The attempt at a solution
i knew how to solve questions one and three..please help me in question number 2...here is what i did...
Question 1
(2*pi*x)/(wavelength)=pi/3
where x is the distance between the two waves (5cm)
and therefore we get the wavelength = 30cm
Question 2
(2*pi*x)/30 - wt = difference in phase
(2*pi*x)/30 - (2*pi*f)(7.5*10^-3) = difference in phase
is this correct,,if so how can i get x ..because i think it would be different
Question 3
v = wavelength * frequency
= 0.3*45
