<span>it will be changed by changing the medium of the wave</span>
Answer:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far fro
Explanation:
You are true, Stokey. The correct choice is<em> (c)</em>.
If you think about it a little bit more, you'll realize that "side to side" is also a horizontal motion.
Anyway, the question told us that we're only talking about 2 dimensions. Well, the The measurements in the 2 dimensions are the x and the y . If there were a z measurement, that would be the 3rd dimension.
I don’t see any answer choice but the best way is asking questions about the natural phenomenon, making hypothesis, and predicting the consequences in the hypothesis.
Answer:
Sharper images will be produced by the new telescopes.
Construction and maintenance is expensive
Explanation:
The telescopes are put in space so that unfiltered light is received by the telescope. Telescopes on Earth receive light after the light has passed through our atmosphere. This affects the final image of the telescope.
Some of the telescopes being planned in the future are the Extremely Large Telescope (ELT) with mirror aperture diameter of 39.3 m, Thirty Meter Telescope (TMT) with mirror aperture diameter of 30 m, Giant Magellan Telescope (GMT) with mirror aperture diameter of 24.5 m. These mirrors have a significantly larger mirror aperture diameter than the space telescopes. The ELT will be able to produce an image 16 times sharper than the Hubble Telescope. It is also very expensive to make an maintain a telescope in space.
Keeping all this in mind the new telescopes are being made on Earth.
