A transmission diffraction grating with 600 lines/mm is used to study the line spectrum of the light produced by a hydrogen discharge tube with the setup shown above. The grating is 1.0 m from the source (a hole at the center of the meter stick). An observer sees the first-ord...

How do I determine the horizontal distance traveled by water passing through a hole of a punctured water bottle. You must use bernoulli's and Kinematics, and find delta x in term of h and y. ( y = the height of water inside the bottle , h = the height of the hole to the fl...

Solved it thank you

The fundamental of an organ pipe that is closed at one end and open at the other end is 261.6 Hz ( middle C ). The second harmonic of an organ pipe that is open at both ends has the same frequency. What are the lengths of the pipe? I tried solving it and I got 0.65 and 0.98 an...

Thanks the answer was right, I related it to the small mass and it made sense ,, I submitted it , and it was right
Physics
No I didn't get it right :S ,, I did it like this exactly ( 0.0095 + 1.45 ) sqrt ( 2*9.8*0.124) = 0.0095 vi
