Answer :
Wien's regulation dictates that to dodge extraterrestrial beings you're able to take the shortest direction to cover (ideally stocked with numerous ray weapons). From this we can discover the the wavelength of image voltaic that's keeping off extraterrestrial beings (could be all of them simply by fact extraterrestrial beings are frightening and minus some brave souls they're going to all be fleeing) and all of us understand that de Broglies equation states that each physique mater has a wave property. applying wavelength = h/mv we can see that each image voltaic would be shifting on the perfect wavelength to dodge extraterrestrial beings, which all of us understand is pi. From this pi wavelength we can then be certain the colour of the image voltaic that's exactly rhubarb (my own well-liked form of pie).
