three cards with holes are arranged in a straight line. a light is shined through the first cards 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
Answer
# Brief Explanations:
When light passes through holes in three - aligned cards, it shows that light travels in a straight line. Reflection involves light bouncing off a surface, and refraction is the bending of light when it passes from one medium to another. Since the light passes through the holes in a straight - line path, it demonstrates rectilinear propagation of light.
# Answer:
C. that light travels in a straight line
