• Q13
What is the purpose of using a white card in the GCSE infrared required practical?
30s
• Q14
What is the relationship between the temperature of an object and the amount of infrared radiation it emits?
The temperature has no effect on the amount of infrared radiation emitted
The higher the temperature, the less infrared radiation it emits
The higher the temperature, the more infrared radiation it emits
The temperature determines the color of the infrared radiation
