Three cards with holes are arranged in a straight line. A light is shined through the first card’s hole and travels through all
three cards. What does this tell you about light rays? A) that light is reflected B) that light is refractive C) that light travels in a straight line D) that light does not travel in a straight line
The fact that the light shone through the first card hole travels through all three cards shows that light travels in a straight line. This phenomenon is known as the rectilinear propagation of light.
If uninterrupted, light shone at one cardhole moves straight through all the cardholes in a straight line.
