According to the rayleigh criterion, what is the shortest object we could resolve at the 25.0 cm near point with light of wavele
Blizzard [7]

Answer:

6.71 *10^{-5} rad

Explanation:

∅ = \frac{1.22*wavelength}{D} = \frac{1.22*550 * 10^{-9} }{25 * 10^{-2} }

∅ = 6.71 *10^{-5} rad

The minimum resolvable angle = 6.71 *10^{-5} rad

Ubes have sides of equal lengths. What is the fastest way to measure the volume of a cube-shaped table?
Kryger [21]

The quickest technique to calculate the volume of a cube-shaped table is to use a ruler to measure one side, then multiply that figure by three. Option B is correct.

<h3 /><h3>How do you calculate the volume of a cube?</h3>

Assume the side length of the cube under consideration is L units. The volume of the cube is then equal to L³ cubic units.

The volume of a cube is;

V = L³

Ubes have equal-length sides. The quickest technique to calculate the volume of a cube-shaped table is to use a ruler to measure one side, then multiply that figure by three.

Hence option B is correct.
