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.

P.E = mgh
This is the formula for potential energy.
This is where m is mass, g is the acceleration due to gravity, and h is height.
All you have to do is multiply all these numbers together.
In spring mass system we know that angular frequency is given as

f = 8.38 Hz


now we know that speed of SHM at its extreme position is given by

here we know that
A = 17.5 cm


so maximum speed is 9.21 m/s
