Astronomers observe a nebula using a variety of telescopes. Suppose they observe wavelengths of 14 cm (radio), 652 nm (red), 1.40 m (infrared), 420 nm (violet), and 131 nm (ultraviolet). Arrange these from fastest speed to slowest speed in empty space. cm = 10-2 m (centimeters), m = 10-6 m (microns), and nm = 10-9 m (nanometers). Group of answer choices There is not enough information to determine the speeds. 1.40 m, 14 cm, 131 nm, 420 nm, 652 nm 14 cm, 1.40 m, 652 nm, 420 nm, 131 nm 131 nm, 420 nm, 652 nm, 1.88 m, 14 cm They all travel at the same speed
