Assume the helium-neon lasers commonly used in student physics laboratories have power outputs of 0.250 mW. (a) If such a laser beam is projected onto a circular spot 2.70 mm in diameter, what is its intensity (in watts per meter squared)? w/m2 (b) Find the peak magnetic field strength (in teslas). T (c) Find the peak electric field strength (in volts per meter). V/m [−14 Points] OSCOLPHYS2016 25.6.P.041. A certain slide projector has a 150 mm focal length lens. (a) How far away is the screen (in m), if a slide is placed 156 mm from the lens and produces a sharp image? m (b) If the slide is 21.0 by 42.0 mm, what are the dimensions of the image? (Enter your answers from smallest to largest in cm.)
