The color that is refracted the most has the___ wavelength

Answer:

The color that is refracted the most has the shortest wavelength

Explanation:

The warmer colors (yellow to red) have shorter wavelengths and the colder (green to violet) shorter wavelengths. Bearing in mind that light is radiant energy, the shorter the wavelength, the greater the frequency and the greater the amount of energy, allowing colors with shorter wavelengths to be more refracted.

The light can reflect in several ways but it follows a law: the angle of incidence is the same as the starting angle. If the light reflects on a perfectly smooth surface, such as in a mirror (which is glass with a silver film), the light will be reflected exactly as it did. That is why we see an image totally faithful in form and color when we see ourselves in the mirror. But if the object is not smooth, it will reflect part of the incident light and absorb the rest. The illumination of this object will reveal only its own color, shape, texture and not the image of a reflection. Black objects absorb light completely and white objects reflect it completely. The colorful visual sensation of objects, in fact, is the detection and perception of the wavelength that they are reflecting.

According to Einstein's special theory of relativity, in which frames of reference will all laws of physics apply?
kenny6666 [7]

Answer: Within any frame of reference that is accelerating

Special relativity was proposed on 1905 by Einstein, who developed his theory based on the following two postulates:

1. <em>The laws of physics are the same in all inertial systems. There is no preferential system. </em>

2. <em>The speed of light in vacuum has the same value for all inertial systems. </em>

Focusing on the first postulate, it can be affirmed that <u>any measurement on a body is made with reference to the system in which it is being measured</u>.

Now, taking into account that an inertial reference system is the one that complies with the principle of inertia:

<em>"For a body to have acceleration, an external force must act on it."</em>

The correct answer is  

Within any frame of reference that is accelerating

A capacitor is connected to an ac generator that has a frequency of 2.3 kHz and produces a rms voltage of 1.5 V. The rms current
miv72 [106K]

Answer:

Explanation:

Given that,

AC frequency of 2.3KHz

f=2.3×10³Hz

Vrms produce is

Vrms=1.5V

Current rms

Irms= 31mA

The capacitor is reconnected to a generator of frequency

f=4.8KHz =4800Hz

The current rms becomes

Irms= 85mA

Vrms=?

Solution

First genrator

The capacitive reactance is given as

Xc=Vrms/Irms

Xc=1.5/31×10^-3

Xc=48.39 ohms

Now, to know the capacitance of the capacitor

Xc=1/2πfC

Then,

C=1/2πfXc

So,

C=1/2×π×2300×48.39

C=1.43×10^-6C

C=1.43μF

Note: the capacitance of the capacitor did not change,

Now for generator two.

The reactance are given as

Xc=1/2πfC

Xc=1/2×π×4800×1.43×10^-6

Xc=23.19ohms

Then,

Vrms2=Irms2 ×Xc

Vrms2=85×10^-3×23.19ohms

Vrms2=1.97V

Vrms2=1.97Volts
