The best description of the Electromagnetic Spectrum is --

• different wavelengths of energy all having the same speed of light and the same frequency

• different frequencies of energy having the same speed of light and the same wavelength

• different frequencies of energy having the same speed of light and different wavelengths

• the same frequencies of energy having the same speed of light and the same wavelength

• sideways

• circular

• perpendicular

• parallel

Why is the light bulb not lighting up in the image shown?

• it needs a wire connecting points A and B

• it needs a wire connecting points C and D

• it needs a wire connecting points D and A

• the light bulb is broken and needs replacing

If a student puts a switch at point 1, what will happen to the light bulbs?

• both will go out when turned off

• only one closest will go out

• only the one farthest away will go out

• nothing will happen

What is the difference between these two circuits?

• parallel circuit has all the bulbs on the same wire and series circuit has the bulbs separated on their own wires

• parallel circuit has the bulbs separated on their own wires and series circuit has the bulbs on the same wire

• there is no difference between them

• the battery is in a different place
