In a double-slit arrangement the slits are 1.80 x 10-5 m apart. If light with wavelength 600 nm passes through the slits, what will be the distance between them=2 and m=5 maxima on a screen 1.00 m away?
Find it's wavelength, frequency, speed, and direction of propagation. Calculate the displacement y of a point on a string at x = 0.015m at t=0. Note that the angle of the sine function is in radians.
If the force in the x direction is 60 N, and the force in the y direction is 150 N, find the acceleration in the x-direction, the y-direction, and the net resultant acceleration.
