It is better to turn it off, the start up current in a light bulb will never exceed the power consumption over a five minute period. A motor shouldn't even be left on for that same reason. (Yes there is a start up current in a light bulb, it's just extremely small.) Your bulb will last longer if you leave it ON. Its the on/off cycle that kills bulbs. Electricity wise; you may save a few pennies a month by shutting it off. True, bulbs do loose life if constantley turned on and off, but you would have to turn it on and off hundreds of times for this to be an issue. A more serious issue would be where the bulb is located,for example a light bulb next to a door will not last as long as a light bulb in the middle of the room, simply because of the shock from the door closing. It is still best to turn the light off, esspecially if its a long life bulb.

Sun is 8 light minutes away how long would it take to send a microwave to the sun and back to earth?
Since microwaves are invisible light (like everything on the electromagnetic spectrum: UV X-rays, infra-red, and so on), it travels at the speed of light. Then, if you send a microwave to the sun, it would be there 8 minutes later, and would take another 8 minutes to come back to earth. So the answers is 16 minutes.

When voyager 2 will be 1 light year away from sun?
Ooh. Long time. In 35 years, V2 has only gotten about 15 light-minutes away. A back of the envelope calculation suggests that another 1.2 million years ought to do it. Edit :It's a lot more than 15 light minutes away. Jupiter is further than that.
What do astronomers mean when they say when you look out into space you are looking back in time?
The light from our own sun takes roughly 8 minutes to travel the distance to us. That means when you look up at the sun (don't do that without special glasses) you are looking at the sun as it was 8 minutes earlier. Or you can say you are seeing the sun 8 minutes back in time. The stars which are far away galaxies, the light takes years to reach us. So the light we see at night now can be 100 years old. Or we are seeing that galaxy as it was 100s of years ago.

Well, some things in the engine can cause a premature light to come on when it is not suppose to. Heres how you can turn that light off... and if it comes back on then you know you need to have your engine checked. Take off the positive wire on your cars battery, leave it off for 1 minute. Reattach, and start your car. Leave your car running for 3-5 minutes. If your light remains off, then you had a false light. If it comes on, get it looked at!
