s2008m [1.1K]3 years ago
6 0

Answer:

I would think the answer is color, if the wavelength is within the visible light spectrum. This could be answered in different ways but I'm pretty sure the answer you are looking for is hue/color.

Irina-Kira [14]

Answer:

The time constant τ = L/R represent the time requiered for the curent to get value of 63 % of its maximun value

Explanation:

In a circuit RL ( serie circuit with a resistor R and the inductor L ) when a voltage is applied the inductor will have a reaction, such reaction consist in the creation of an electromotive force which will prevent the current to get its maximun value. The time constant which in the case of an inductor is

τ = L/R ,  represent the time requiered for the crrent to be 63 % of its final value

Which information is necessary to determine an object's speed?
lana [24]

Answer:

1. distance and period of time.

Explanation:

The speed is calculated using the formula k = \frac{d}{t}

"k" is the speed, "d" is the distance and "t" is the time.

You need distance and time to calculate the speed.

Speed is how fast an object is going. The direction is irrelevant to speed, not to be confused with velocity, which is speed in a given direction.

Consider light energy that is momentarily absorbed in glass and then re-emitted. Compared to the absorbed light, the frequency o
fredd [130]

The frequency of the re-emitted light is identical to that of the absorbed light.

To find the answer, we need to know more about the frequency of light.

<h3> Why the re-emitted light has the same frequency?</h3>
  • The wavelength of the light that is momentarily absorbed in glass and then re-emitted is the same, which explains why the re-emitted light has the same frequency as the absorbed light and the frequency of the absorbed light is the same.
  • An electromagnetic wave's energy is inversely related to its frequency.
  • The relationship between the wave's wavelength and frequency depends on the speed of light:

                              frequency=\frac{c}{wave length} , c is the speed of light.

  • Despite not having mass, light still has energy, and that energy is conserved.
  • As a result, in order for there to be energy conservation, the energy of the light that is received and reemitted must be equal.

Thus, we can conclude that, the re-emitted light's frequency matches the absorbed light's frequency.

If the ultraviolet photon has a wavelength of 249 nm and one of the photons emitted by the fluorescent material has a wavelength
melamori03 [73]

Answer:

601 nm

Explanation:

Energy of photon having wavelength of λ nm

= \frac{1244}{\lambda}eV

Energy of 249 nm photon

=\frac{1244}{249}

=4.996 eV

Similarly energy of 425nm photon

=\frac{1244}{425}

=2.927 eV

Difference = 2.069 eV.

This energy will give rise to another photon whose wavelength will be

λ = \frac{1244}{2.069}

= 601 nm.

What would a plot of p versus 1/v look like for a fixed quantity of gas at a fixed temperature?
Romashka-Z-Leto [24]

Answer:

Straight Line

Explanation:

For an ideal gas,

PV = nRT

For a fixed quantity ( constant number of moles) of a gas at fixed temperature

Right side of the equation will be constant

Thus,

PV = C

So, P = \frac{C}{V} .

Thus P is directly related to \frac{1}{V}

That's why plot between P and  \frac{1}{V} will be an straight line.
