Answer:
The wavelength is 503 nm
Explanation:
Considering constructive interference , this means that route(path) difference is equal to the product of order of fringe and wavelength of the light
i.e dsinθ = m
Where is the wavelength of light and m is the order of the fringe
Looking at θ to be very small , sin θ can be approximated to θ
and
Substituting this into the above equation
making x the subject
This above equation will give the value of the distance of the order fringe of the wavelength from the central fringe
Replacing with the value given in the question we have
= 710 nm m = 2 d =0.66 mm , l = 2.0 m
The separation of the second fringe from central maximum is 4,303 mm
To obtain the separation of the second order fringe of the unknown light from central maximum
Now to obtain the wavelength of this second source
from
Now substituting 3,053 mm for 2.0 mm for l , 0.66 mm for d and 2 for m in the above formula
Answer:
Gravitational field strength =weight/mass
Explanation:
14.8N/4.0kg
3.7N/kg
The solution for this problem is:The charge would be now equal to:(electric constant) multiplied by the (field strength) multiplied by the (area) so plugging in our values, will give us:8.85 * 10^-12 As / (V * m) * 3 * 10^6 V/m * 0.055 m^2 = 1.46 e-6 amperes would be the answer
The fastest nerve signals travel at speeds that exceed 100 meters per second :)
