1
Q

What did Ritter discover?

A

Ultraviolet radiation

2
Q

What was the only part of EM spectrum we knew of before Herschel’s discovery?

A

Visible light

3
Q

What did Herschel do?

A

Herschel used a prism to create a spectrum on a screen

He then used a thermometer to measure each colours temperature

4
Q

In Herschel’s discovery, what were the temperatures?

A

The temperature of each colour was different, but the temperature increases from violet to red

5
Q

After finding the temperature of each colour, what did Herschel do next?

A

He then measured the temperature just past the red part of the spectrum where there was no visible light
Here he found the highest temperature of all, so he realised this high temp must of been cause by a type of infra red radiation

6
Q

What did Herschel find?

A

Infra red radiation
