The coolest and dimmest space objects emit radiation of longer wavelengths than those we can see. A detector for which type of electromagnetic radiation is most suitable to study cool dim stars?

1. Gamma ray
2. Infrared
3. Ultraviolet
4. X-rays

Respuesta :

The answer is 2. Infrared

Answer:

A detector for infrared radiation is most suitable to study cool dim stars.

Explanation:

  • Stars that are cool and dim have been observed to emit infrared radiation.
  • The wavelength of infrared radiation can range from 700 nanometers to 1 millimeter.
  • Radiations with a wavelength as small as this can only be emitted by small, dim and cool stars.
  • Thus, a detector for infrared radiation is most suitable to study cool dim stars.
