How wide is the central diffraction peak on a screen 2.10 m behind a 0.0328-mm-wide slit illuminated by 568-nm light?

Physics

Answer:

0.0364 m

Explanation:

D = Screen distance = 2.10 m

d = Slit width = 0.0328 mm = 0.0328 x 10⁻³ m

\lambda = Wavelength of light = 568 x 10⁻⁹ m

w = width of the central diffraction peak

Width of the central diffraction peak is given as

w = \frac{D \lambda}{d} \\w = \frac{(2.10) (568\times10^{-9})}{0.0328\times10^{-3}}\\w = 0.0364 m

suter [353]

The largest distance moved by a particle of a vibrating body from its equilibrium position is called amplitude. Wave B has higher energy because wave it has a higher amplitude.

<h3>What is the amplitude of a wave?</h3>

The largest distance moved by the particles on either side of the mean position is the amplitude of a wave.

The maximum height of either crest or trough from its equilibrium position is called amplitude.

Hence Wave B has higher energy because it has a higher amplitude.

To learn more about the amplitude of a wave refer to the link;

Two solid spheres are made from the same material, but one has twice the diameter of the other. Which sphere will have the great
aivan3 [116]

Answer:

It will be the same for both

Explanation:

from this question we have one similarity between these two spheres.

- they are both made from the same material,

The difference between both spheres is that:

- one of the spheres has its diameter to be twice as large as that of the other one.

We are to say the sphere with the greater bulk modulus.

If the material is the same thenthe Bulk modulus is also the same. It is not dependent on the material since it is a constant for that materia

Therefore the correct answer is:

It will be the same for both spheres.
