•  A) A red 650 nm laser is pointed into a block of glass with an index of refraction of 1.5. What angle will the laser refract to if the incident angle is 0 degrees (straight perpendicular), 30 degrees, 45 degrees?
• B) A red 650 nm laser is pointed out of a block of glass with an index of refraction of 1.5. What angle will the laser refract to if the incident angle is 0 degrees (straight perpendicular), 30 degrees, 45 degrees?
