The unpolarized light becomes less intense. When unpolarized light is run through a polarizer, its intensity is diminished by a factor of ½.
<h3>Unpolarized light:</h3>
Unpolarized light is diminished by a factor of ½ when it travels through a polarizer. Cos 2θ averages out across all angles to be ½ in size. I transmitted = I₀ and ½ I₀ at all angles The unpolarized light's intensity decreases to zero.
The light-producing atoms on the heated filament's surface behave independently of one another. Each of these emissions can be roughly represented as a brief "wave train" lasting between approximately 109 and 108 seconds. These wave trains, each with its unique polarization direction, are superimposed to form the electromagnetic wave that is coming from the filament.
Unpolarized light is produced by all common light sources, including the Sun, incandescent and fluorescent lighting, and flames.

Answer:
8954000 J
Explanation:
The formula to find kinetic energy is:
<em>Kinetic energy = </em>
<em> × mass × (velocity)²</em>
So, Kinetic energy = × 370 × (220)²
Kinetic energy = 8954000 J
Answer:
You hang a 350 gram mass on a spring and its displaced 0.5 cm. Its spring constant is
Answer:
D. 3 psi
Explanation:
Pressure is defined as force acting per unit area and is numerically expressed as:
where P represent pressure, F is force and A is area where the force acts. Substituting 300 lb for force and 100 sq.in for area then pressure,
Therefore, from the choices given, option D, 3psi is the right choice.
I., II., and IV. are examples of acceleration. III. isn't.
