Explanation:
Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.
So by using the equation of diffraction,
dsinA = nL
SinA is a geometric component it can be written as,
∵ x is the distance from screen.
∵ y is the half of the width of central maximum.
now by putting the values in mm,
d = 2.15× mm
Answer:
La potencia de la bombilla es de 1056 W.
Explanation:
La potencia de la bombilla se puede calcular usando la siguiente ecuación:
En donde:
P: es la potencia
I: es la corriente = 2,4 A
V: es la diferencia de potencial = 440 V
Entonces, la potencia es:
Por lo tanto, la potencia de la bombilla es de 1056 W.
