Consider an experiment using a diffraction grating with 7000 lines/cm, a screen 2.50 m away, and a 440-nm wavelength beam of light. a) how many side maxima will be observed on one side of the central maximum? (hint: the largest m when q = 90°)
b) what is the angle formed by the first-order bright spot and the central maximum?
c) how far apart on the screen are the first-order and second-order maxima on the same side of the central maximum?

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.

Why can blue light and yellow light combine to produce white light? question 17 options: they are both primary colors of light. they absorb each other's wavelengths. because blue, yellow, and white are primary colors. they are complementary colors of light.
