Homework Statement A vertical spring, fixed at the upper end, has a mass attached to the lower end. When the spring is given a small extension it was observed to oscillate at a rate of 45 cycles per minute. When an additional 160g mass is attached to the spring, it oscillated at a rate of...

y=\lambdaD/a is that the maximum signal strength

i only have 2 formulas Constructive interference: r1 - r2 = m\λ ,m = 1,2,... Destructive interference:r1 - r2 = (m + 1\2)λ ,m = 1,2,...

I understand what's is going on here...my problem is finding a formula to solve this..I have an exam next Monday and I need to know this...

Guys i appreciate it and all but i sill can't get this.. i understand what constructive and destructive interference is but what does it have to with the signal strength

yes..i know that destructive interference is when a trough and a crest of 2 different met and cross out each other and constructive interference is when 2 waves forms of the same phase met and create a bigger wave

ok so i got the formula for calculating the bright fringes...i put in the variables and i get 65.6km but that still does not explain the signal strength

seriously that didn't help..but thanks

Homework Statement Two radar transmission towers located 6.4 km apart emit identical signals of wavelength 420 meters. A ship located at a point 30 km equidistant from the towers experiences a strong signal from the towers. However, as it sails parallel to the line of the towers it...
