The index of refraction of a material is the ratio between the speed of light in vacuum, c, and the speed of light in that material, v:
where the speed of light in vacuum is
. The speed of light in benzene is
, so we can use the previous relationship to find the refractive index of benzene:
Answer:
If one bulb goes out, other bulbs stays lit.
If there is break in one branch of the circuit, current can still flow through other branches.
Parallel circuits are simple to design and build.
Explanation:
In parallel circuits all the components and resistors are connected to common terminal or common supply.
So here if we disconnect one of the branch of the circuit then it will not affect the other branches of the circuit so it will not affect the current of other branches.
So here it is very easy to build a parallel circuit and if one of the branch of the circuit goes out then it will not affect the other branches.
Its speed decreases, its wavelength increases, and its frequency Remains the Same.
X-ray formation
Energy difference in the first ionization of the same group of elements
Differential linear emission spectra of different elements
Explanation:
The formation of x-ray, energy difference in the first ionization of the same group of elements and differential linear emission spectra of different elements can be justified by the Bohr model of the atom.
- According to Neil Bohr, in an atom, the extranuclear part consists of electrons in specific spherical orbits around the nucleus.
- Bohr's model explained the discrete lines in atomic spectrum of different elements.
- Due to excitation of electrons, some rays are given off. Some of these are energetic like x-rays.
- The energy difference between the first ionization of the same group of elements is a proof that electrons are in specific spherical orbits.
- The higher the energy the level, the ease at which electrons can be removed and the lower the ionization energy.

Answer:
209.66 m
Explanation:
Given:
Original length of the spaceship, L = 481 m
Speed of the spaceship, v = 2.70 × 10⁸ m/s
Now,
using the concept of length contraction, we have
where,
L' is the observed length
c is the speed of the light
Thus,
on substituting the respective values, we get
or
L' = 209.66 m
