So, the frequency of that light approximately [tex] \sf{\bold{3.53 \times 10^{14} \: Hz}} [/tex]
IntroductionHi ! I will help you to explain the relationship between velocity of electromagnetic waves in a vacuum with frequency and wavelength. We all know that all of the type of electromagnetic wave, will have the same velocity as the speed of light (because the value is a constant), which is 300,000 km/s or [tex] \sf{3 \times 10^8} [/tex] m/s. As a result of this constant property, the shorter the wavelength, the greater the value of the electromagnetic wave frequency. This relationship can also be expressed in this equation:
[tex] \boxed{\sf{\bold{c = \lambda \times f}}} [/tex]
With the following condition :
c = the constant of the speed of light in a vacuum ≈ [tex] \sf{3 \times 10^{8} \: m/s} [/tex] m/s[tex] \sf{\lambda} [/tex] = wavelength (m)f = electromagnetic wave frequency (Hz)Problem SolvingWe know that :
c = the constant of the speed of light in a vacuum ≈ [tex] \sf{3 \times 10^{8} \: m/s} [/tex] m/s[tex] \sf{\lambda} [/tex] = wavelength = 850 nm = [tex] \sf{8.5 \times 10^2 \times 10^{-9}} [/tex] m = [tex] \bold{8.5 \times 10^{-7} \: m} [/tex]What was asked :
f = electromagnetic wave frequency = ... HzStep by step :
[tex] \sf{c = \lambda \times f} [/tex]
[tex] \sf{3 \times 10^8 = 8.5 \times 10^{-7} \times f} [/tex]
[tex] \sf{f = \frac{3 \times 10^8}{8.5 \times 10^{-7}}} [/tex]
[tex] \sf{f \approx 0.353 \times 10^{8 -(-7)}}} [/tex]
[tex] \sf{f \approx 3.53 \times 10^{-1} \times 10^{15}} [/tex]
[tex] \boxed{\sf{f \approx 3.53 \times 10^{14} \: Hz}} [/tex]
Conclusion :So, the frequency of that light approximately [tex] \sf{\bold{3.53 \times 10^{14} \: Hz}} [/tex]

How can you remove energy from matter? Question 10 options: By increasing its volume By lowering its temperature By increasing its pressure By boiling it.
Answer: YA i got u!!! got 20/20, so its correct
Explanation:
By lowering its temperature, you can remove energy from matter.
What is thermal energy?Thermal energy is the energy that is generated by the movement of particles in matter. It is a form of kinetic energy that results from the motion of atoms or molecules in a substance. The faster the particles move, the more thermal energy they have. Thermal energy can be transferred from one substance to another by conduction, convection, or radiation. It is a fundamental aspect of many physical processes, including thermodynamics and heat transfer, and is central to the study of energy and its applications in science and engineering.
As the temperature of a substance decreases, the motion of its molecules and atoms also decreases, which results in a decrease in its thermal energy.

What is Kirchhoff law?
Kirchhoff's Current Law states that the total current entering a junction or a node equals the charge leaving the node as no charge is lost.
According to Kirchhoff Current Law for parallel circuits,
The pair of leads connecting all the branches to the voltage source terminals is the main line. All the current in the circuit must come from one side of the voltage source and return to the opposite side for a complete path. The amount of current in the main line is equal to the total of the branch currents. The total current that flows from the power supply and back.The total current in the main line is equal to the sum of the branch currents.This is known as Kirchhoff’s current law (KCL).It applies to any number of parallel branches, whether the resistances in those branches are equal or not.Therefore,
The current that flows from and back to the power supply in a parallel circuit is called Mainline current current.
