Answer:
Light waves can travel with and without mediums.
Explanation:
Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;
I. The wavelengths of light range from 400 nm to 700 nm.
II. Light waves are transverse waves.
III. The speed of light is 3 x 10^8 m/s.
<em>Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.</em>
This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
Answer:
Solar panels fight global warming by producing electricity that keeps us from burning greenhouse gas-producing fossil fuels. They also shade Earth from the sun.

Answer:
Explanation:
That's quite a bit of points. Offer 20 next time (which shows up as 10).
Not all experiments lend themselves to this, but the best ones do. Make predictions. The startling experiments (the best of them) certainly allow you to make predictions
Most of the time, experiments confirm what was originally thought. It is, however, the best answer among this bunch.
A is also possible, but not always. I will stick with D, but I think others will pick A.
