1

Which part of the burner is used to adjust the amount of gas flow and the height of the flame?

A

B

1

Which position around the flame has the hottest temperature?

position A

position B

position C

position D

1

In this image, is the gas flowing or is the gas turned off?

The gas is turned on and flowing.

The gas is turned off.

What is the purpose of a diffraction grating?

to break light into its component parts

to give energy to create the light

to make the light brighter

1

Why does each transition have a different wavelength and color?

To make the picture pretty. All emitted light is actually white.

The wavelengths are random and could be any value.

The distance of each transition is different, so the energy change is different for each transition.

1

Do any of the elements emit the exact same set of colors?

no

yes

1

Do any elements emit the entire rainbow?

Yes

No

1

Which part of the atom is active during the emission of the bright-line spectrum?

electrons

electrons and protons

neutrons

protons

1

An electron will emit energy when it changes its position in what way?

as the electron jumps up to a higher energy level

as the electron falls down to a lower energy level
