Answer:
pha của dao động là hàm bậc nhất của thời gian.
Wind is primarily driven by differences in air pressure. These variations in air pressure are due to temperature differences caused by variations in solar energy received at the surface of the Earth.
Answer:
Δx = 2.76 x 10⁻³ m = 2.76 mm
Explanation:
The distance between any two consecutive dark or consecutive bright fringes is given by:
Δx = λL/d
where,
Δx = distance between first and second dark fringe = ?
λ = wavelength of light = 546.1 nm = 546.1 x 10⁻⁹ m
L = distance between slits = 1.35 m
d = slit separation = 0.267 mm = 2.67 x 10⁻⁴ m
Therefore,
Δx = (546.1 x 10⁻⁹ m)(1.35 m)/(2.67 x 10⁻⁴ m)
<u>Δx = 2.76 x 10⁻³ m = 2.76 mm</u>
