Aphysics instructor wants to produce a double-slit interference pattern large enough for her class to see. for the size of the room, she decides that the distance between successive bright fringes on the screen should be at least 3.00 cm. if the slits have a separation d=0.0200 mm, what is the minimum distance from the slits to the screen when 632.8 nm light from a he-ne light is used?

How have the competing explanations' experiments on atoms affected the development of the atomic model?

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
