Question

d. Match each term to its correct description.

A. Refraction
B. Diffraction
C. Reflection
D. Constructive interference
E. Destructive interference

_____ The superimposition of waves to create a wave with a larger amplitude

_____ The superimposition of waves to create a wave with a smaller amplitude

_____ The bending of a wave as it enters a different medium

_____ The bending of a wave around an obstacle

_____ The bouncing of a wave off a surface

Answer 1

any ideas so far? for example, does constructive interference make a larger or smaller amplitude?

Answer 2

anyway, you kind of have to know this, but constructive interference = larger amplitude (think "construction", like building something bigger) and destructive interference = smaller amplitude (like destroying something)

Answer 3

__D___ The superimposition of waves to create a wave with a larger amplitude

__E___ The superimposition of waves to create a wave with a smaller amplitude

_____ The bending of a wave as it enters a different medium

_____ The bending of a wave around an obstacle

_____ The bouncing of a wave off a surface

Answer 4

good, any ideas about the others? like, when light "reflects" off of something is it bouncing off, bending, or entering the medium?

Answer 5

refraction would be the third one

Answer 6

A+ well done

any ideas about the others?

__B___ The bending of a wave around an obstacle

_C____ The bouncing of a wave off a surface

Answer 8

well done
