Explanation:

• Option a: Visible light is a common way astronomers observe many astronomical objects, so this is true.
• Option b: X - ray telescopes are designed to detect X - ray radiation, not all six types of electromagnetic radiation. Different telescopes are used for different parts of the electromagnetic spectrum, so this is false.
• Option c: Infrared radiation is related to heat, and infrared telescopes can detect the heat (infrared radiation) given off by astronomical objects, so this is true.
• Option d: Telescopes that capture microwaves and radio waves, like radio telescopes, can have a satellite - dish - like appearance (e.g., large parabolic dishes), so this is true.

Answer:

a. Astronomers are able to use visible light to view most all astronomic objects, c. Infrared telescopes are used to detect the heat given off astronomic objects, d. Telescopes that capture microwaves and radio waves look like satellite dishes
