`\huge\boxed{\sf Option \ 3}`

Step-by-step explanation:

Spectroscope:

• The device used to tell the properties of the spectral lines in an electromagnetic spectrum is called spectroscope.

Properties of spectroscope:

• For any space object, spectroscope tells:

1. Type of element the object is made of.
2. Temperature of object.
3. Chemical composition.
4. Speed
5. Magnetic and electric field.

• Spectroscope also can tell the light intensity and their wavelength.
