The distance of the Earth from the Sun is: d = 1.5 × 108 km = 1.5 × 1011 m The refractive index of water is: μ = 1.346 The refractive index (μ) is defined as: μ = speed of light in vacuum / speed of light in the material = c / v Thus, the speed of light in water is: v = c / μ Given: c = 3 × 108 m/sRead more
The distance of the Earth from the Sun is:
d = 1.5 × 108 km = 1.5 × 1011 m
The refractive index of water is:
μ = 1.346
The refractive index (μ) is defined as:
μ = speed of light in vacuum / speed of light in the material = c / v
Thus, the speed of light in water is:
v = c / μ
Given:
c = 3 × 108 m/s
Calculate the speed of light in water:
v = 3 × 108 m/s / 1.346 = 2.229 × 108 m/s
The time taken by light to reach the Earth when traveling through water is:
time = d / v = 1.5 × 1011 m / 2.229 × 108 m/s = 0.673 × 103 s
Convert the time to minutes:
t = 673 s
t = 673 / 60 min = 11.22 min
Final Answer:
The time taken for light to reach the Earth when the medium is water is:

Have you ever seen a spider that looks like it has a splash of sunshine? That’s the Joro spider, scientifically known as Trichonephila clavata. These orb-weavers are known for their striking yellow and black bodies. Originating from East Asia, they are found in countries like China, Japan (excluding Hokkaido), Korea, and Taiwan.
Joro spiders are the architects behind the impressive wheel-shaped webs you might notice in gardens or forests. With their legs fully extended, they can measure up to 3 inches (8 cm) – nearly the length of a ruler.

Your question is interesting and quite common for people looking to hire a freelance developer for their projects.
After researching online and talking with developer friends, I’ve put together a list of things to keep in mind when hiring a freelance developer:
Experience Matters: Look for someone with real-world problem-solving experience, not just memorized programming knowledge. Be cautious of those who only know how to use AI tools to build software—it can cause issues down the road.
Problem Understanding: A good developer will understand the business problem first and then create software to solve it. Make sure they get what you’re trying to achieve.
No Language Barrier: Clear communication is key. Ensure there are no language barriers that could distract from the real needs of the project.
Payment Quotes: Be aware of those who quote a price before fully understanding your needs and project details. It’s a sign of inexperience.
Finished Projects: Portfolios are nice, but ask to see actual completed projects that are live. If a project isn’t live, ask why.
Agreeing to Everything: Some developers might agree to everything you say. This often shows their inexperience. You want someone who can give you honest feedback and realistic timelines.

The sun is 1.5×108km from Earth. The index of refraction for water is 1.346. How much longer would it take light from the sun to reach Earth if the space between them were filled with water rather than a vacuum?
