Humans have evolved so that their eyes are most sensitive over the same wavelength range at which the Sun emits the greatest intensity of radiation. However, the Predator\'s (From the movie The Predator) vision is best in the infrared. Is the Predator\'s home star hotter or colder than or Sun? Explain your reasoning, and draw a rough blackbody spectrum of the Sun and a rough blackbody spectrum of the Predator\'s home star to illustrate your point. Be sure to label the x-axis and y-axis on each spectrum.

Solution

The wavelength that Predator can see is infrared radiation having higher wavelength than the visible light.

The star is cooler than sun as the radiation emitted by it is having lower frequency.
