Understanding Light Travel from the Sun to Earth

The video tutorial explains how to calculate the time it takes for light to travel from the Sun to the Earth. It begins by introducing the problem and the known values: the distance between the Sun and Earth and the speed of light. The tutorial then walks through the calculation process, including converting units from miles to meters and using the formula for constant speed to find the time in seconds. Finally, it converts the time from seconds to minutes, concluding that light takes approximately 8.3 minutes to travel from the Sun to Earth. The video also encourages viewers to ask questions and explore additional resources for further learning.

What is the approximate distance from the Sun to the Earth in miles?

• 93 thousand miles

• 93 million miles

• 150 thousand miles

• 150 million miles

What is the speed of light in meters per second?

• 3 x 10^9 m/s

• 3 x 10^6 m/s

• 3 x 10^8 m/s

• 3 x 10^7 m/s

Which formula is used to calculate the time taken for light to travel a certain distance?

• D = T/V

• V = D/T

• T = D/V

• D = VT

Why is it necessary to convert miles to meters in this calculation?

• To avoid using kilometers

• To use a different formula

• To make the calculation easier

• To match the units of speed and distance

What is the converted distance from miles to meters?

• 1.496 x 10^11 meters

• 1.5 x 10^10 meters

• 1.496 x 10^10 meters
