Answer:
9654.34 m
Explanation:
from conservation of momentum
And from Conservation of Energy
Answer:
A is glass, B is air, and C is water
Explanation:
n_air < n_water < n_glass
This makes sense, since solids are denser than liquids, and liquids are denser than gases. Refractive index generally increases with density.
Snell's law states:
n₁ sin θ₁ = n₂ sin θ₂
What this means is the higher the index of refraction n, the lower the angle of incidence θ.
Media A has an angle of incidence of 15°.
Media B has an angle of incidence of 26°.
Media C has an angle of incidence of 21°.
Therefore, A is glass, B is air, and C is water.
Answer:
The minimum thickness of the soap bubble for destructive interference to occur is 225.56 nm.
Explanation:
Given;
wavelength of light, λ = 600 nm
The minimum thickness of the soap bubble for destructive interference to occur is given by;
where;
n is refractive index of soap film = 1.33
Therefore, the minimum thickness of the soap bubble for destructive interference to occur is 225.56 nm.
Answer: columbs
Explanation:
Electrical charge are measured in columbs, usually demoted as C. Hence, the charges on proton and electron will be measured in Coloumbs. It typically measures the amount of electricity conveyed per second by a current of 1 ampere. The other units Given such as ; Volt is used for measuring voltage, which is the pressure in an electrical source. AMPERE is used for measuring the current flowing through an electrical circuit.
Dalton is a unit of mass and is about 1.660 * 10^-27 kg
