Answer:
The law of reflection states that the angle of incidence = the angle of reflection.
Explanation:
Reflection is the phenomenon that occurs when a ray of light hits the boundary between two media and it is reflected back into the first medium.
In such a situation, we call:
- angle of incidence: it is the angle between the direction of the incident ray and the normal to the surface
- angle of reflection: it is the angle between the direction of the reflected ray and the normal to the surface
There is a precise relationship between the angle of incidence and the angle of reflection. In fact, the Law of Reflection states that:
- The incident ray, the reflected ray and the normal to the surface all lie within the same plane
- The angle of reflection is equal to the angle of incidence
Answer:
10042.6 ohm
Explanation:
f = 10 kHz = 10000 Hz, L = 36 mH = 0.036 H, R = 10 kilo Ohm = 10000 ohm
C = 5 nF = 5 x 10^-9 F
XL = 2 x π x f x L
XL = 2 x 3.14 x 10000 x 0.036 = 2260.8 ohm
Xc = 1 / ( 2 x π x f x C) = 1 / ( 2 x 3.14 x 10000 x 5 x 10^-9)
Xc = 3184.7 ohm
Total impedance is Z.
Z^2 = R^2 + (XL - Xc)^2
Z^2 = 10000^2 + ( 2260.8 - 3184.7 )^2
Z = 10042.6 ohm
