Question 1

Order of the electromagnetic spectrum

Answer 1

Radio. Raging
Microwaves Martians
Infa-red Invade
Visible Venus
Ultra violet Using
X-ray X-ray
Gamma Guns

Question 2

Radio to gamma what happens

Answer 2

Increase in energy
Decrease in wavelength
Increase in frequency

Question 3

Quanta

Answer 3

Energy can only be absorbed or released from atoms in certain amounts

Question 4

What is an emission spectroscopy

Answer 4

Spectrum is examined to see the wavelength emitted

Question 5

What is an absorption spectroscopy

Answer 5

Light of certain wavelengths is absorbed and electrons are promoted to higher energy levels

Question 6

What does the number of lines on the spectrum relate to

Answer 6

How many different electron transitions are possible

Question 7

Explain how a line emission spectrum is formed

Answer 7

Electrons are promoted. They then fall to a lower level and a photon of light is emitted.

Question 8

Explain why there is a series of lines at discrete wavelengths

Answer 8

Due to the different transitions available

Question 9

What happens when the concentration of solution increases

Answer 9

The intensity of radiation absorbed also increases
