(True / False) A straight wave heads into a curved surface. It will reflect so that the wave scatters
(True / False) When a straight wave pases through a small opening, it produces a small straight wave.
(True / False) Unless it is disturbed each point on a wave will travel along either a straight or curved path.
(True / False) When an wave hits a barrier, the angle that it reflects depends on its speed.
(True / False) As a wave changes media its speed changes.
(True / False) Two waves traveling through the same medium meet, they will bounce off each other and change direction.
(True / False) The speed of a wave is determined by its medium.
(True / False) Defraction is the bending of a wave because its speed changes.
(True / False)As the frequency of a wave increases, its wavelength increases.
(True / False) During refraction, a wave bends because it hits the edge of a barrier.
----------------
Here's my best answers for all of them.
1. T - a curved surface will make a wave bend
2. T - a small opening will make the wave be small
3. F - it will travel on a straight path if undisturbed
4. F - the angle depends on the barrier angle
5. T - speed is determined by media
6. F - the two waves will not necessarily change direction
7. T - speed is determined by media
8. F - diffraction is bending because of a barrier
9. F - frequency and wavelength are inversely related
10. F - refraction bends a wave because of media change
