kolezko [41]

Answer:

measuring the zero intensity point, we can deduce the movement of the screen.

The distance from the center of the pattern to the first zero is proportional to the distance to the screen,

Explanation:

The expression for the diffraction phenomenon is

           a sin θ = m λ

for the case of destructive interference. In general the detection screen is quite far from the grid, let's use trigonometry to find the angles

           tan θ = y / L

     

in these experiments the angles are small

          tan θ = sin θ / cos θ = sin θ

          sunt θ = y / L

we substitute

          a \frac{y}{L}= m  λ

           y = m L λ / a

therefore, by carefully measuring the zero intensity point, we can deduce the movement of the screen.

 

The distance from the center of the pattern to the first zero is proportional to the distance to the screen, so you can know where the displacement occurs, it should be clarified that these displacements are very small so the measurement system must be capable To measure quantities on the order of hundredths of a millimeter, a micrometer screw could be used.

Which three terms are needed to describe the energy a BASE jumper has as she falls toward the ground?
Thepotemich [5.8K]

Answer:

Potential energy

Kinetic energy

Gravitational energy.

Explanation:

The potential energy is the stored energy, it is the energy and object posses at rest. When the base jumper is still at rest i.e without motion, she has potential energy.

Gravitational energy this refer to the potential energy an object or body with mass posses in relation to another object due to gravity.

This is seen when the base number is still at rest and the force of gravity on the Earth acting on her.

Kinetic energy is the energy posses by an object or body in motion.

As the base jumper falls to the ground, she posses kinetic energy which is the energy in motion.
