GCSE Physics – Absorbing and emitting
Learning Objectives
-I can describe that objects absorb and transmit light of different wavelengths
-I can explain that the intensity and wavelength distribution depends on the temperature of the object
-I can explain anybody is constantly absorbing and emitting radiation, and the balanced between the two determines the temperature
-I can explain how radiation affects the temperature of the Earth
-I can explain how different surfaces absorb and emit radiation
