At what speed, as a fraction of c, will a moving rod have a length 65% that of an identical rod at rest

dezoksy [38]

Answer:

v/c = 0.76

Explanation:

Formula for Length contraction is given by;

L = L_o(√(1 - (v²/c²))

Where;

L is the length of the object at a moving speed v

L_o is the length of the object at rest

v is the speed of the object

c is speed of light

Now, we are given; L = 65%L_o = 0.65L_o, since L_o is the length at rest.

Thus;

0.65L_o = L_o[√(1 - (v²/c²))]

Dividing both sides by L_o gives;

0.65 = √(1 - (v²/c²))

Squaring both sides, we have;

0.65² = (1 - (v²/c²))

v²/c² = 1 - 0.65²

v²/c² = 0.5775

Taking square root of both sides gives;

v/c = 0.76

An incident electromagnetic wave is polarized and its E vector has a maximum value of 6 Volts/m. It is incident on a polarizer w

adell [148]

To solve this problem it is necessary to apply the equations related to the law of Maus.

By the law of Maus we know that

$I = I_0 cos^2 \theta$

Where,

$I_0$ = Intesity of incident light

I = Intensity of polarized light

With our values we have that

$I_0 =$ 6V/m

$\theta = 45\°$

Then

$I = 6*cos^2(45)$

$I = 3V/m$

Therefore the maximum value of the transmitted E vector is 3V/m
