4-3 Waves and EM Waves Standard Quiz

Mrs. Henry attended this summer band concert to hear her son play his violin. When she sat down in their seats, she noticed that there were dead moments. That is, places in the music when she could not hear anything! She decided to move and sit directly in front of the band in the third row. How can you explain the dead spots they experienced?

• Some sound waves cancelled each other out.

• Some of the students stopped playing for a few seconds.

• The sound waves underwent constructive interference.

• Sound waves reflected off of the ceiling and walls.

Isaac Newton in his 1670's lectures on optics and later in his 1704 publication Opticks, he described light as composed of ________ in his corpuscular hypothesis arguing that the perfectly straight lines of reflection demonstrated this nature.

• waves

• lines

• particles

• reflections

There are two seemingly inconsistent models of light. One model suggest light is pure energy wave and the other suggests that light is made up of particles or photons. How would you explain the results when white light passes through a prism and is split into different colors?

• White light is made up of waves that can transform themselves.

• White light is made up of particles of many colors.

• White light is made up of waves of different frequencies.

• White light is made of particle and white particle are blocked by the prism.

Maddy, 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.

• There will be no change in either wave.

• Wave A will cancel out wave B and amplitude will be 0.

• A new wave with smaller amplitude than A or B will be the result.

• A new wave with larger amplitude than A or B will be the result.
