Explanation:
The equation that gives the position of the maxima (bright fringes) in the interference pattern produced on a distant screen by the diffraction of light through two slits is
where
y is the distance of the maximum (bright fringe) from the central maximum
m is the order of the maximum
is the wavelength of the light used
D is the distance of the screen
d is the separation between the slits
In this problem we have:
is the separation between the slits
D = 3.30 m is the distance of the screen
m = 1 (we are analyzing the 1st bright fringe)
is the distance of the 1st bright fringe from the central maximum
Solving for , we find the wavelength of the light used:
Explanation:
According to ohm's law, current flowing through a conductor is directly proportional to the voltage over resistance.
Mathematically, I =
where, I = current
V = voltage
R = resistance
It is given that value of voltage is 120 V and current is 1.5 ampere. Therefore, calculate the resistance as follows.
I =
or, R =
=
= 80 volts per ampere
= 80 ohms
Hence, resistance of the lamp is 80 ohms.
