### Sound is a disturbance that travels through a medium as what kind of wave

longitudinal wave

outer space

### The speed of sound depends on

the properties of the medium

elasticity

intensity

infrasound

pitch

frequency

### The changing pitch of a police car's siren as it moves by you is an example of

diffuse reflection

concave

### This happens when light passes from air into water

the light slows down

### This happens when white light strikes a black object

Red, green, blue

Pigments

Magnetic poles

### This happens if you break a magnet in half

Each half will be a new magnet (with a north & south pole)

Repel each other

Magnetic field

### Magnetic field lines around a bar magnet do what

Spread out from the poles & curve around the magnet

Magnetic field

### The charge on a proton and electron

Proton=positive Electron=negative

Repel each other

### The buildup of charges on an object is called

Static electricity

Static discharge

### After you acquire a positive charge, you then touch a doorknob & receive a shock. This leaves you

Electrically neutral

Voltage

### An electric current will always follow

The path of least resistance

### In a series circuit with 3 bulbs

All the bulbs become dimmer as more bulbs are added

### In a parallel circuit with 3 bulbs

Current from each bulb has its OWN path to follow

Example:
