The sunlight - or, more precisely, the photons that comprise the sunlight that’s striking the Earth right now, has spent the past 8 minutes and 20 seconds Light takes about 8 minutes to travel from Earth to the sun. Electromagnetic Waves To understand how light travels from the sun to the Earth, you have to understand what light is. This is also the amount of time it takes for sound to travel from the Earth to the moon.

Earth is at a distance of 150 million km (Approximately) or $150\times10^9$ m Speed of light is $3\times 10^8$ m/s Hence time required for light to reach from sun to earth is [math]t=\dfrac{x}{v}=\dfrac{150\times There are many

The sun is a burning ball of gas very very far away in space (Picture: Getty) And how long does it take in earth terms for this light to reach us from the sun? The time it takes to travel those steps is the total distance divided by the speed of light. How much time will the light take to cover a distance of 9.2 × 107 miles? So, if you think photons only travel 0.1 millimeters between crashes, it will take more than half a million years for the photon to escape the Light from the Sun takes about 5 and 1/2 hours to reach it and roughly the same time to return to Earth. It takes light from the moon's surface approximately 1.3 seconds to reach the Earth. Light is an electromagnetic wave--a wave of electric and magnetic energy oscillating very quickly.

Well, it may not be exactly 30,000 years old - but it is old alright. That means that communication from the Earth … Light from the sun travels to Earth at a speed of 1.86 × 105 miles/second.
