Predict what color red paper will appear under white and red light.Red paper will appear black under red light and red under white light.Red paper will appear red under red light and black under white light.Red paper will appear red under both red and white light.Red paper will appear red under red light and white under white light.120s
- Q8Mr. and Mrs. Tew attended this summer band concert to her their son play his violin. When they sat down in their seats, they noticed that there were dead moments. That is, places in the music when they could not hear anything! They decided to move and sit directly in front of the band in the third row. How can you explain the dead spots they experienced?Sound waves reflected off of the ceiling and walls.The sound waves underwent constructive interference.Some sound waves cancelled each other out.Some of the students stopped playing for a few seconds.120s
- Q9Maddy, Carole, and Maria are enjoying a day at the beach. They are body surfing and playing on their boards. Imagine that wave A catches up with wave B. Describe the change, if any, in wave amplitude.Wave A will cancel out wave B and amplitude will be 0.A new wave with larger amplitude than A or B will be the result.There will be no change in either wave.A new wave with smaller amplitude than A or B will be the result.120s
- Q10Together, the cornea and the lens work to help us see. What is an important function of these two parts of your eye?Together they refract light to help the eye focus.Together they control the amount of light that enters the eye.Together they magnify the light that enters the eye.Together they invert the image we see on the retina.120s
