In the ray model of light, light will travel in a straight line until Select all that are true. it decides it wants to turn around and go back home it reflects at an interface it scatters within a medium O it refracts at an interface O its momentum reaches a maximumQuestion 1 A Helium discharge lamp gives off two wavelengths 604 nm and 500. nm. The diffraction grating has 413 lines/mm that is observered on a screen that is 2.00 m away. What is the distance between the first order fringes of the two different wavelengths? O 1.96 m O 5.04x10-10 m O 0.0931 m O 3.14m Question 2 Minor h Wall -Laser beam At what angle does the laser beam need to be at to hit the mirror then hit the midpoint of the wall? The height of the room is h = 2.70m and the width of the room is w = 4.50 m. O 1.19 rad O 0.733 rad O 1.03 rad O 0.540 rad Question 3 An object is 19.0 cm from a diverging lens and the object is 0.700 cm tall. What is the position and height of the image if the focal length of the lens is -59.0 cm? O The object is at -0.0696 cm and the height of the image will be 0.00256 cm upright. The object is at -14.4 cm and the height of the image will be 0.531 cm upright. O The object is at -0.0696 cm and the height of the image will be 0.531 cm inverted. O The object is at -14.4 cm and the height of the image will be 0.00256 cm inverted
