Q

What is Refraction?

A

The bending of waves as they enter a new medium

The bending occurs due to the change in speed of the wave

17
Q

Pitch

A

A

Current

20
Q

What is the way you calculate resistance in a parallel ?

A

Some of respircuals

21
Q

What is the constant of the parallel?

A

Voltage

22
Q

What is the electrochemical cells?

A

Piece of metal sitting in an electrolyte

23
Q

What is the Electrolyte?

A

A substance,Liquid or paste that conducts electrician current

24
Q

What is the Terminal?

A

The part of the electrode that sticks out of the electrolyte

25
Q

Electrode?

A

A piece of metals sitting I the electrolyte

26
Q

Who was Galvani?

A

Was dissecting a frog on an iron table
When he touched a brass to the iron while the hook was stuck in a muscle, there was a spark where the two metals made contact

27
Q

Who was Volta.

A

Used Galvani’s research to make the first battery

The reaction was caused by s combination of the iron railing, brass hook and salty fluids in the frogs
