Electromagnetic Spectrum

Question 1

What is the electromagnetic spectrum ?

Answer 1

It’s a spectrum of the ranges of electromagnetic radiation

Question 2

What’s is electromagnetic radiation?

Answer 2

Energy that is transmitted as waves with a spectrum of DIFFERENT frequencies

Question 3

What happens as you go along the electromagnetic spectrum?

Answer 3

-Decrease in wavelength
-Increase in frequency/energy

Question 4

What is an acronym to memorise the spectrum

Answer 4

RICH MEN IN LOVE USE X-tra GEL

Question 5

What are the types of waves across

Answer 5

-radio waves
-microwaves
-infrared waves
-visible LIGHT
-ultraviolet
-X-rays
-GAmma rays

Question 6

What happens when electrons absorb or realise energy in fixed amounts?

Answer 6

The atoms move energy levels

Question 7

Explain what happens when atoms absorb or realise energy

Answer 7

-atoms are at the ground state which is lowest energy level
-if atoms take in energy form surroundings —> ELECTRONS GET EXCITED
-move to a higher energy level
-election release energy drop from higher energy level to lower
-all energy levels have FIXED values

Question 8

What is formed when electrons move up or down energy levels ?

Answer 8

Two types of spectra are formed
: absorption and emission

Question 9

Describe absorption spectra

Answer 9

-Dark lines On a coloured background
- electrons ABSORBS certain frequencies(related to energy)

Question 10

What does it mean when the spectra absorbs different frequencies!

Answer 10

There will be differences in energy levels

Question 11

Describe emission spectra

Answer 11

-coloured lines On a Dark background
-RELEAES energy

Question 12

Are the frequencies in the same element different?

Answer 12

No the frequencies missing are the same

Question 13

What does each element have and what does this mean?

Answer 13

Each element has a different electron arrangement
-frequencies absorbed and emotes are different
-Spectrum for each element is unique
