Light of wavelength 400 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 x10-5 m. The distance among the grating and the viewing screen is 0.10 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing).
(a) Decide the distance y from the central bright fringe to the second-order bright fringe.
(Hint: The diffraction angles are small enough that the approximation tan(θ) ~sin(θ) can be used.)
b) If the entire apparatus is submerged in water (nwater= 1.33), what is the distance y?
A lightbulb is 48 cm from a convex lens, and its image appears on a screen located 31 cm on the other side of the lens. By how much is the image enlarged or reduced
An event occurs at x′ =60m, t′ =8×10-8 sec in a frame S′ (with y′ =0, z′ = 0). The frame S′ has a speed of 3c/5 in the x direction with respect to frame S. The origins of S and S′ coincide at t = 0, t′ = 0. What are the spacetime coordinates of th..
The drawing shows three identical rods (A, B, and C) moving in different planes. A constant magnetic field of magnitude 4.50 T is directed along the +y axis. The length of each rod is L = 1.3 m, and the speeds are the same, vA = vB = vC = 2.9 m/s. Fo..
