Admin in charge of the past questions and answers shld pls go through all the mistakes ,is getting too much
The ans is 1 not 2
Reasons
The distance between two adjacent node in a stationary wave is half wavelength π/2 and not full wavelenght as in π,so when solving we got 2cm as the wavelength since they ask the dist. Btw adjacent nodes you will divide it by 2 and the ans will give u 1cm
Pls check that again
Can you imagine? 5 wrong answers for this exam now,not cool.....
Distance b/t a node an the next antinode= π/4
Distance b/t two successive nodes or antinodes= π/2
Distance between three success nodes or antinodes= π
Pls changes still has not been made.
U worked out 2.0cm as the answer bt mar ked 1.5cm..i think this is getting too much for my liking..Try and make some changes in all the errors.
