A material that transmits nearly all the light that strikes it
is described as being "transparent", but that has nothing
to do with "resistance to the light", whatever that is.
Even the blackest, densest material, like wood, foil, or concrete,
has no "resistance" to light. It simply absorbs light that enters it,
so some or all of the light that went in one side never made it to
the other side.
Transparent material absorbs very little, so almost all of the
light that goes in one side comes out the other side.
Answer:
W = 750 [J]
Explanation:
The question should be related to work, work in physics is defined as the product of force by distance. In this way, we can use the following equation.

where:
F = force = 30 [N]
d = distance = 25 [m]
W = work [J]
Now replacing:
![W=30*25\\W=750 [J]](https://tex.z-dn.net/?f=W%3D30%2A25%5C%5CW%3D750%20%5BJ%5D)
<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
Answer:
D) 1000 m/s
Explanation:

You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Hope this helps.
