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.

Refraction and reflection both shows the wave property of light and the difference between them is that during reflection the medium of light will not change while in refraction the light will change its medium
so in reflection of light we use that angle of incidence = angle of reflections with respect to normal
While in refraction we use Snell's law
![n_1sin\theta_1 = n_2 sin\theta_2](https://tex.z-dn.net/?f=n_1sin%5Ctheta_1%20%3D%20n_2%20sin%5Ctheta_2)
Diffraction of light is the phenomenon of light in which light will bend at the corners and enter into the region of dark
While absorption is the phenomenon of energy absorption when light incident on any medium or surface
Answer:
Length will be 0.491 nm
Explanation:
We have given wavelength of the photon ![\lambda =800nm=800\times 10^{-9}m](https://tex.z-dn.net/?f=%5Clambda%20%3D800nm%3D800%5Ctimes%2010%5E%7B-9%7Dm)
Plank's constant ![h=6.6\times 10^{-34}J-s](https://tex.z-dn.net/?f=h%3D6.6%5Ctimes%2010%5E%7B-34%7DJ-s)
We know that energy of the photon is given by
![E=\frac{hc}{\lambda }=\frac{6.6\times 10^{-34}\times 3\times 10^8}{800\times \times 10^{-9}}=2.475\times 10^{-19}J](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bhc%7D%7B%5Clambda%20%7D%3D%5Cfrac%7B6.6%5Ctimes%2010%5E%7B-34%7D%5Ctimes%203%5Ctimes%2010%5E8%7D%7B800%5Ctimes%20%5Ctimes%2010%5E%7B-9%7D%7D%3D2.475%5Ctimes%2010%5E%7B-19%7DJ)
We know that energy of photon is also given by
![E=\frac{n^2h^2}{8mL^2}=\frac{h^2}{8mL^2}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bn%5E2h%5E2%7D%7B8mL%5E2%7D%3D%5Cfrac%7Bh%5E2%7D%7B8mL%5E2%7D)
![2.475\times 10^{-19}=\frac{(6.6\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times L^2}](https://tex.z-dn.net/?f=2.475%5Ctimes%2010%5E%7B-19%7D%3D%5Cfrac%7B%286.6%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%20L%5E2%7D)
![L=0.491\times 10^{-9}m](https://tex.z-dn.net/?f=L%3D0.491%5Ctimes%2010%5E%7B-9%7Dm)
Answer:
