The sun rising every morning. Its' light traveled about 93,000,00 miles through a vacuum in order to be seen.
If you accept that the space between the Earth and the Moon is lacking in atmosphere, that is, its a pretty good vacuum, then the simple fact that you can see the Moon (and Sun and Stars) is enough proof for me.

Give an example of when the normal force on an object is less than mg?
When you are traveling up an incline.
What is the frequency of light in fused quartz if the wavelength in vacuum is 500nm?
Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.
Give 5 example of energy transformation?
refrigarator-electrical energy-light energy-heat energy
What object doesn't give out light?
Anything that you can't see in a dark room. Like my shoes, for example.
Is there a wavelength for electricity?
Sure, if it is AC (alternating current), you can calculate a wavelength. For example, in copper the speed is roughly 2/3 the speed of light in a vacuum, that is, 200,000 km/sec.; electricity in our homes comes at a frequency of 50 or 60 cycles per second; so (assuming the frequency of 50 cycles), that would give you a wavelength of 200,000 km/sec / 50 Hertz = 4000 km.Sure, if it is AC (alternating current), you can calculate a wavelength.

Can you give me example of light energy?
light in a microwave, infrared light, and gamma rays.

Is vacuum the only medium for light to travel?
No. Light also travels through air, water and glass, to give just a few examples.
How does the sun give its energy to the Earth when space has no gravity?
The light travel directly through the vacuum and reaches earth
Give example of light energy that is not produced by electricity?
Gas light, kerosene lantern.
Can you give an example of a sentence using the word 'demonstrate'?
You'll have to demonstrate the vacuum cleaner before I'll consider buying it.
What is the value of c in a vacuum Give the numerical value as well as the definition?
C represents the speed of light. In a vacuum it is 299,792,458 meters per second. C is also the maximum speed at which anything in the universe can travel.
What causes light to refract Give an example form everyday life?
Sex
Give an example of a chemical change that produces light and heat?
you fart on a candle....
If the speed of light in a vacuum is 1.2 times that of the speed of light in a given material what is the index of refraction for that material?
2 (no units)
Could you give me a sentence for vacuum?
I seek the vacuum of space. Who'll vacuum the living room? That's a powerful vacuum cleaner.
