The spectrum Year 8 Science

Learning objectives Comment on the position of the light spectrum on the electromagnetic spectrum State that different colours have different wavelengths Separate out the colours of white light using a prism

The electromagnetic spectrum

The visible spectrum Identify the colour has the longest wavelength? Identify the colour has the shortest wavelength Predict the colour that will be refracted the least by a prism. Explain your answer

Prisms Use the ray box to pass a beam through the prism State the effect of the prism Comment on you prediction – Were you correct? Photograph your spectrum. The best one will be published

The visible spectrum Draw the prism and spectrum List the colours with shortest wavelength first
