Q

Explain why it is important for someone who goes spear fishing to know what refraction is.

A

If they don’t know what refraction is they are not going to know how to re adjust and they won’t catch anything.

Q

What is an application of constructive interference that we have discussed in class? Explain how it works.

A

Constructive interference is when two waves combine with each other and make a bigger an example of this is the viking clap.

What is ROYGBIV

A

Red, Orange, Yellow, Green, Blue, Indigo, and violet these colors make up visible light.

25
Q

Wave

A

A disturbance that transfers energy from place to place.

26
Q

Transverse wave

A

The energy makes the wave move up and down.

27
Q

Longitudinal wave

A

The particles oscillate along the direction in which the wave is traveling.
