This resource is a complete lesson that covers Stellar Spectra for the OCR A Level Physics A course. However, it is useful for other exam boards too.

This lesson teaches the following content:
-energy levels of electrons in isolated gas atoms
-the idea that energy levels have negative values
-emission spectral lines from hot gases in terms of emission of photons and transition of electrons between discrete energy levels
-the equations hf = ΔE and hc/λ = ΔE
-continuous spectrum, emission line spectrum and absorption line spectrum
-transmission diffraction grating used to determine the wavelength of light
-the condition for maxima: dsinθ = nλ, where d is the grating spacing
-different atoms have different spectral lines which can be used to identify elements within stars

This lesson includes:
-A full presentation including 2 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
