Red shift of distant galaxies
Space telescopes must be placed in orbit around earth in order to observe short-wavelength radiation.
<h3>What is telescope?</h3>
A telescope is an optical instrument that uses lenses, curved mirrors, or a combination of both to watch distant objects.
When atoms in a gas reach this temperature, they travel so quickly that when they collide, they release X-ray photons with wavelengths smaller than 10 nanometers.
Because the Earth's atmosphere prevents all X-rays from space, these wavelengths must be seen using space telescopes.
To study short-wavelength radiation, space telescopes must be put in orbit around the Earth.
Hence, space telescope is the correct answer.

The partial pressure of the O2 is 36.3 kiloPascal when the air pressure in the mask is 110 kiloPascal based on the isotherm relation. This problem can be solved by using the isotherm relation equation which stated as Vx/Vtot = px/ptot, where V represents volume, p represents the pressure, x represents the partial gas, and tot represents the total gas<span>. Calculation: 33/100 = px/110 --> px = 36.3</span>
Answer:
width of slit(a)≅ 0.1mm
Explanation:
Wave length of laser pointer =λ = 685 nm
Distance between screen and slit = L = 5.5 m
Width of bright band = W=8.0cm=0.08m
width of slit=a
recall the formula;
W=(2λL)/a
a=2λL/W
a=(2 *685*10⁻⁹*5.5m)/0.08m
a=7535*10⁻⁹/0.08
a=94187.5 *10⁻⁹
a=0.0000941875m
a=0.0941875mm
a≅0.1mm
