Answer: 25 m
Explanation:
The resolving power of a telescope is given by:
Diameter of the telescope = 10.0 m
Wavelength of the telescope = 550 nm = 550 ×10⁻⁹m
Thus, the resolving power of one of telescopes at the Keck Observatory is:
Also,
separation between objects = tan (3.85×10⁻⁶)° × 3.8×10⁵km = 2.5 × 10⁻²km =25 m
Answer:
infrared waves
radio waves
ultraviolet waves
Explanation:
Radio waves are used for communication such as television and radio.
Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark.
Ultraviolet radiation can kill bacteria that are present in water - this sterilises the water and makes it safe to drink.
