372,564.7941 miles.
1,079,252,850 km or in other words a very very long way
In vacuum, that would be 181,314,478,600 kilometers (112,663,593,700 miles). (both rounded) It would be perfectly proper, and a lot more convenient, to call that distance "1 light-week".
By far the hottest of the two light sources is the light bulb.
Light travels at about 343 meters per second in air. With a 2-second delay, the lightning strike would be approximately 686 meters away from you.
Neptune has an average distance from the Sun of 2.8 billion miles and the earth is 0.09 billion miles from the sun so it is 2.71 billion miles from the earth. Light travels at 186,000 miles per second. So 2.71 x 109 divided by 186,000 = 14570 seconds = 4.05 hours = 4.62 x 10-4 years.
The speed of light is about 183,000 miles per second, or just under 300,000 kilometers per second. Radio transmissions, which travel at the speed of light, can go from the earth to the moon in under two seconds, but it would take them almost nine minutes to reach the sun. As far as distance, no one has ever theorized that light stops traveling, if unimpaired by a solid substance. It's presumed that it can travel to the known edges of the universe, but it can take it billions of years to get there.

A light year is the distance that light can travel in a year.5,865,696,000,000 miles or 9,460,800,000,000 kilometresThis can be worked out because we know how far light travels in a second (186,000 miles per second / 300,000kilometers per second), we can therefore use simple maths to work out the answer.186,000 miles/second x 60 seconds/minute x 60 minutes/hour x 24 hours/day x 365 days/year = 5,865,696,000,000 miles/year.

When a light ray is incident perpendicular to the boundary between two transparent materials, the angle of refraction is 0 degrees. This means that the light ray continues to travel in a straight line without bending when entering the second material.
