Answer:
Explanation:
Given:
width of the wire,
thickness of the flat wire,
length of the wire,
voltage across the wire,
current through the wire,
Now the net resistance of the wire:
using ohm's law
We have the relation between the resistivity and the resistance as:
where:
a = cross sectional area of the wire
resistivity of the wire material
Answer:
Explanation:
Let consider the observer as an inertial reference frame. The object is modelled after the Principle of Momentum Conservation:
The speed of the more massive piece is:
The kinetic energy added to the system is:
The distance between two successive troughs or crests is known as the wavelength. The wavelength of the light will be 1000 nm.
How do you define wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
Diffraction angle= 30⁰
Diffraction grating per mm= 250
wavelength = ?
Mathematically the equation of bright band is given by
m
Hence the wavelength of the light will be 1000 nm.
