How many minutes would it take a radio wave to travel from the planet Venus to earth?

radio waves travel at the speed of light (c) ... 3E8 m/s

the distance from Venus to Earth depends on where each planet is in its orbit around the Sun

To calculate the time it would take for a radio wave to travel from Venus to Earth, we need to know the distance between the two planets and the speed of light.

1. Find the distance between Venus and Earth:
The average distance from Venus to Earth varies depending on their positions in their respective orbits. On average, Venus is about 41 million kilometers (25 million miles) away from Earth.

2. Determine the speed of light:
The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second).

3. Calculate the time it takes for the radio wave to travel:
Divide the distance between Venus and Earth by the speed of light to get the time it takes for a radio wave to travel.

Distance / Speed = Time

(41,000,000 kilometers) / (299,792 kilometers per second) = 136.764 seconds

To convert seconds to minutes, divide the result by 60:

136.764 seconds / 60 ≈ 2.279 minutes

Therefore, it would take approximately 2.279 minutes for a radio wave to travel from Venus to Earth.
