Question

Part A How telescopes for invisible wavelengths differ from those for visible light? What other types of "cosmic messengers" can astronomers now observe? Drag the items on the left to the appropriate blanks on the right to complete the sentences. (Items can be used once or more than once.) Reset Help infrared Only the longest wavelengths act enough like the visible wavelengths that we can use neutrino the same sorts of telescopes with different detectors. At the shortest wavelengths, gamma-ray waves actually act more like X-ray telescopes are very similar to optical telescopes, except that they use different cosmic rays detectors to sense the light. ultraviolet Astronomers also have facilities to observe and study radio gravitational waves telescopes use a dish (like a satellite dish) to observe objects. In some cases, several dishes work together to form images at a much higher resolution than any one of them could achieve alone. radiation cannot be focused in the traditional sense. telescopes must contain massive detectors in order to intercept these high-energy photons. telescopes have to gently redirect the light because it tends to go straight through things in its path. mirrors are arranged so that the light just grazes them.

Answer 1

1) Ultraviolet,cosmic rays,gamma rays

2) infrared

3) cosmic rays, gravitational waves, neutrino

4) radio

5) x-ray, x-ray

6) neutrino, infrared

Answer 2

The wavelength range of the ultraviolet waves is 10 nanometers to 400 nanometers. This UV waves shorter than the visible waves but the longest ultraviolet wavelengths act like the visible wavelengths. Gamma rays has more penetration power. Gamma rays have shorter wavelengths. At the shortest wavelengths, Gamma-ray waves act more like cosmic rays. (ii) Infrared light in infrared telescopes used to detect the Celestial bodies. Infrared telescopes are similar to the optical telescopes. (iii) Astronomers also have facilities to observe and study cosmic rays, gravitational waves, and neutrino. (iv) Radio telescope use a satellite dish to observe the objects. Gamma ray radiation cannot be focused in the traditional sense, because they have more penetrating power. Gamma ray telescopes contain massive detectors. (vi) X-rays are tending to travel straight through the objects. So, the X-ray telescopes must gently redirect the light. X-rays are arranged in the x-ray telescope, so, the light can graze them.

5) x-ray, x-ray

6) gamma-ray, gamma-ray
