A piece of metal. I believe it is a piece of metal.
Answer:
the angle, in radians, between the central maximum = 2.87degree or 0.05radians
Explanation:
The detailed steps and appropriate formula is as shown in the attachment.
Using λm = dsin teta
where d =20λ, m = 1
from the formula, sin teta = λ/20λ
= sin teta = 0.05
teta = arc sin(0.05) = 2.87 degree
Answer:
what this please be clear
The light-collecting area of the 10-meter Keck telescope is <u>4 times greater </u>than the light-collecting area of the 5-meter Hale telescope.
Why?
We can calculate the light-collecting area of a telescope by using its diameter/radius. To do that, we can use the following formula:
Now, to know how much greater is the collecting area of the 10-meter keck telescope compared to the collecting area of the 5-meter hale telescope, we need to calculate their light-collecting areas and compare them.
For the 10-meter keck telescope, we have:
For the 5-meter hale telescope, we have:
Now, comparing the areas, we have:
Hence, we have that the light-collecting area of the 10-meter keck telescope is 4 times greater than the light-collecting area of the 5-meter hale telescope.
Have a nice day!
