How long will light radiation take to get from the Sun to the Earth if the distance between them is 150 * 10 ^ 6 km?

Given:
Distance from the Sun to the Earth = 150,000,000 km;
The speed of light (from the reference book) = 300,000 km / sec.

The travel time is determined by the formula:
T = L / V,
Where
T is time;
L is the distance;
V is the speed.

Substituting the values into the formula, we get:
T = 150,000,000 / 300,000 = 500

Answer: The light beam will travel from the Sun to the Earth in 500 seconds.
