Explanation:
Area of the solar sail = A = 30 m2
Solar constant = I = 1388 W/m2
Planck's constant = h = 6.626 × 10⁻³⁴ m²kg/s
Speed of light = c = 3×10⁸ m/s
Wavelength of light = = 570 nm
Pressure from radiation
Energy of a photon
Number of photons
Number of photons is
Answer:
Explanation:
As we know by the formula of diffraction
so we have
a = slit size
= angular position of Nth minimum
so we will have
for first minimum of 630 nm light
Now for another wavelength second minimum is at 60 degree angle
