Silver is best conductor with copper close behind.
best insulator depends on application. Teflon is best for very small currents, ceramic is probably best for high voltage, although a vacuum is also very good.
Answer:
Explanation:
Energy is directly proportional to frequency and it is given as:
E = hf
where h = Planck's constant
f = frequency
To get frequency, we use the formula of speed:
c = λf
where c = speed of light
λ = wavelength
=> f = c/λ
Therefore, the energy of the photon will be:
E = hc/λ
The energy of the photon is
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that the gas equation is given as
so here we know that
Now in order to find the final volume we have
Part b)
Work done in this process is given as
Answer:
Explanation:
. If any other color of light except red strikes the heart it will
appear
The phenomenon that is observed when an incident ray travelling in a slower medium strikes the boundary of a faster medium with an angle greater than the critical angle is known as total internal reflection.
Total internal reflection results in the the ray being reflected within the medium, instead of leaving it after undergoing diffraction. This phenomenon is the working principle of optical fibers.
