Question

1. what happens when a straw looks \bent\ in a glass of water due to light traveling through air and water?

a) reflection
b) refraction
c) diffraction
d) standing wave

1. why can you still hear someone speaking even if they are around the corner from you?

a) interference
b) diffraction.
c) reflection
d) refraction

1. when two waves overlap and create a louder or softer sound, this is called:

a) reflection
b) interference
c) refraction
d) diffraction

1. what type of wave pattern is created when two identical waves travel in opposite directions and combine?

a) standing wave
b) reflected wave
c) refracted wave
d) diffraction pattern

Explanation:

• Question 2: Refraction occurs when light passes from one medium (air) to another (water), changing speed and direction, making the straw appear bent.
• Question 3: Diffraction allows waves (sound) to bend around obstacles (the corner), enabling you to hear the speaker.
• Question 4: Interference is when two waves overlap, resulting in a louder (constructive) or softer (destructive) sound.
• Question 5: A standing wave is formed when two identical waves travel in opposite directions and combine.

Answer:

1. B. Refraction
2. B. Diffraction
3. B. Interference
4. A. Standing wave
