Answer:0.46
Explanation:
Given
Initial height
inclination
Thrust
combined mass of kieran and skis
Speed at the bottom
From Work Energy Theorem
Work done by all the force is equal to change in kinetic Energy
------------1
distance traveled along the slope
substitute in 1
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.
