Answer:
The wavelength of the laser, λ = 5.625 * 10⁻⁷ m
Explanation:
Separation of the narrow slits, d = 7.5 * 10⁻⁵ m
The distance between the screen and the two slits, d = 4m
The distance between the bright spot and the center of the pattern, Y = 1.5 cm
Y = 1.5 * 10⁻² m
To calculate the wavelength, λ, of the laser we will use the relationship:
λ = 5.625 * 10⁻⁷ m
Answer:
Explanation:
The position depends on the time. The longer the time, the further the distance.
Explanation:
In a manual transmission there are three pedals. From left to right, they are: Clutch, Brake, Gas. The clutch is the only pedal you press with your left foot. The other pedals – brake and gas – operate just like they do in an automatic transmission.
