The wavelength of the light that are not reflected in the air is,
λ5= 600 nm, λ6= 500 nm, λ7=428 nm.
<u>Explanation:</u>
- For the above problem, we have the case as no<n1 and n2 < n1 .
- so we have(1<1.5;1.4<1.5)To find the wavelengths of the light that is not reflected in the air.
- Since the phase changes are not common on both the surfaces/
- we have the formula, λ=2d n²/m ( where m=1,2,3,4,5...)
- solving the problem we get,
- λ5= 600 nm, λ6= 500 nm, λ7=428 nm
- The wavelength of the light that are not reflected in the air is,
λ5= 600 nm, λ6= 500 nm, λ7=428 nm.
Answer:
Their kinetic energy will increase but potential energy will decrease.
Explanation:
Given that
Initial velocities of electron and proton is zero.
We know that ,electron have negative charge and proton have positive charge it means that they will attract to each other.We know that opposite charge attract to each other and same charge repels to each other.
It means that the velocities of proton and electron will increase and that leads to increase in the kinetic energy of proton and electron.
We know that potential energy U

So when r will decrease then U will increase but in negative direction it means that U will decrease.
So we can say that their kinetic energy will increase but potential energy will decrease.
Answer:
D
Explanation:
The gravity is pushing the water downward so Wayne could go down but the water is pushing Wayne to go up which would make him float.
Answer: A material that does not easily allow a charge to pass through it is called an Plastic and rubber are good insulators. Many types of electric wire are covered with plastic, which insulates well. The plastic allows a charge to be conducted from one end of the wire to the other, but not through the sides of the wire.
