Question

1. read the paragraph below and select the correct term for each blank.

in various technologies, waves interact with materials in different ways. for example, when light waves bend as they pass through a water droplet to create
a rainbow, this is called - choose the correct answer - . when sound waves bounce off walls in an auditorium to amplify or echo sound, it is known as

• choose the correct answer - . finally, when light waves interact and combine to produce colorful patterns on the surface of a soap bubble, this behavior is

called - choose the correct answer -

• choose the correct answer -

interference
reflection
refraction

Explanation:

1. For the first blank: When light waves bend as they pass through a water droplet (a change in medium), this phenomenon is refraction. Refraction is the bending of waves when they enter a medium where their speed changes.
2. For the second blank: When sound waves bounce off walls (like a mirror bouncing light), this is reflection. Reflection is the bouncing back of waves when they hit a surface.
3. For the third blank: When light waves interact and combine (superpose) to produce patterns (like on a soap bubble, due to thin - film interference), this is interference. Interference occurs when two or more waves meet and combine, creating regions of constructive and destructive interference.

Answer:

First blank: refraction
Second blank: reflection
Third blank: interference
