You need to provide the photon wavelength without which we cannot check your solution.ammar98 said:Homework Statement
Force F acting on a NdYAG laser of 1 kW continuous wave output by the impulse transfer of the photons
Homework Equations
F= dp/dt
The Attempt at a Solution
Photon Energy E=[hc][/λ]=hν
momentum P= [h][/λ]
power of laser 1 kw
at time (t) the laser emit photons
t=[P][/E] = [λ[/hc]
F= dp/dt = t * P = [λ][/hc] * [h][/λ] = [1][/C] = 3.333 x 10 ^ -9 N
can you check please if the solution correct
If P is power (Energy per unit time) then t*P is energy not force. Also 1/c has units of Time/Length which is not units of force.ammar98 said:F= dp/dt = t * P= [λ][/hc] * [h][/λ] = [1][/C] = 3.333 x 10 ^ -9 N
The force F is a physical quantity that measures the interaction between two objects. It is typically represented by the symbol F and is measured in units of Newtons (N).
The force F acting on a NdYAG laser of 1 kW can be calculated using the formula F = P/c, where P is the power of the laser in watts and c is the speed of light in a vacuum.
The force F on a NdYAG laser can be affected by various factors such as the power of the laser, the wavelength of the light, the distance between the laser and the object it is interacting with, and the properties of the object itself.
The force F can impact the performance of a NdYAG laser in several ways. It can affect the stability and accuracy of the laser's output, as well as its ability to interact with objects and produce desired results. It is important to carefully consider and control the force F in order to optimize the performance of the laser.
Yes, there is a maximum force F that a NdYAG laser can produce. This limit is determined by the power and properties of the laser, as well as the physical limitations of the materials used to construct it. It is important to operate the laser within its safe and optimal range to avoid potential damage or malfunction.
