The refractive index of water is listed as 1.3, meaning that the speed of light in water is c/1.3 .
Distance = (Speed) x (Time)
Time = (Distance) / (Speed)
Time to cover distance ''D' at speed 'c' = D/c
Time to cover distance 'D' at speed c/1.3 = 1.3D/c
Difference in time = (1.3D/c) - (D/c) = D/c (1.3 - 1) = 0.3D/c
For the sun and earth, D = 93,000,000 miles, c = 186,282 miles per second
0.3 D / c = (0.3 x 93,000,000) / (186,282) = 149.8 seconds = 2-1/2 minutes more
No, there is no vacuum between Earth and the Sun. The space between Earth and the Sun is filled with the solar wind, which consists of charged particles and electromagnetic radiation. This forms the interplanetary medium, which is not a complete vacuum but very low density compared to Earth's atmosphere.
On average, the distance between Venus and Mars is about 225 million kilometers. Since the speed of light is about 300,000 kilometers per second in a vacuum, it would take about 12.5 minutes for a beam of light to travel from Venus to Mars.
as electromagnetic radiation
The space in our solar system is filled mostly with vacuum, meaning it is mostly empty of matter. There are some particles, such as gas and dust, but they are sparsely distributed. The solar system is defined by the gravitational influence of the Sun, which keeps the planets and other objects in orbit.
The space between planets is known as interplanetary space. It is mostly vacuum but can contain small amounts of particles and gases.
Aristotle was a proponent of the idea that a vacuum cannot exist because, in his view, nature abhors a vacuum. He believed that there can be no empty space between particles because all space must be filled with matter. This idea was later overturned by modern physics and the concept of a vacuum in quantum mechanics.

Light bulb is filled with inert gas or simply a vacuum.
I got out the vacuum and began, rather glumly, to clean the carpets...
no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
Maybe about 45 minutes to let the car cool down, so you can uninstall the vacuum pump between the firewall and attached to the back of the engine (upper rear left/passenger side) which will take you about 30 minutes if replacing a new vacuum pump, and up to one hour if you replace the three gaskets only.

a manometer or vacuum gauge
Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon. The earliest bulbs weren't filled with any gas, but had vacuum inside.
If the system is being completely filled, a vacuum will have to be pulled on the system. If the system just needs to be topped off then a vacuum pull is not needed.
