Consider a star whose surface temperature is only 3000 Kelvin. Draw an illustration of the relationship between this star's intensity and its colour. The y-axis should be intensity, and the x-axis wavelength. Be sure your sketch shows the visible band of wavelengths, and also shows why this star has an orange-red appearance to the eye. Also on the same diagram include a curve for a star of temperature 10000 Kelvin and the Sun for comparison.
