Answer:
755 x 10⁻⁷ m
Explanation:
D = distance of screen
=2. m
d is width of slit = ?
wave length λ = 566 nm
Width of central maxima = 2 λD /d
= 3.00 x 10⁻² =2 λD /d
= 754.67 x 10⁻⁷ m .
= 755x 10⁻⁷ m
Nicholas Copernicus, Greek astronomer, was the one who famously proposed the heliocentric theory -- the theory by which the sun was in the center of the solar system and the planets orbited it circularly.
Hope I helped and good luck!
The problem describes the relationship of "bulb a" and "bulb b" to be in connected in series. When the switch is open then no current can flow, on the other hand, when it is closed, current will pass through.
When only "bulb a" is connected to the battery then more current is flowing to "bulb a" causing it to be bright.
Closing the switch would mean that "bulb b" is already included in the circuit and the battery will push small current to flow around the whole circuit. The more bulbs are connected, the harder for the current to flow because the resistance will be very high.
So the light of "bulb a" will be dimmer.
