Continuous spectra
- Contain all posible frequencies
- hot objects release more of one frequency than an other this wavelength is called peak frequency.
- The peak frequency emitted by an object depends on its temperature, the higher the temperature the more energy the photons radiated will have and so higher the peak frequency
-the luminosity or brightness also depends on temperature the hotter they are the more they glow. For example we can tell how hot a star is by looking at its colour Red = Low frequency & so is a cool star (not as in a star made of ice but cooler than the average star) Blue = higher frequency and so is a hotter star. Our star is fairly cool so is Yellow.
