What is the relationship between wavelength of light and the quantity of energy per photon?
slamgirl [31]

Answer:

The quantity of energy per photon is inversely proportional to the wavelength of the light.

Explanation:

Energy of light is given as

E = hf

where E = energy of the photons,

f = frequency of the light

If the number of photons = n

(E/n) = (h/n) f

Let (E/n) = E'

(h/n) = h'

But the frequency of light is related to wavelength through the relation

v = fλ

where v = speed of light = c

λ = wavelength of light

f = (c/λ)

E' = h' f

Substituting for f

E' = h' (c/λ)

h' and c are both constants, h'×c = K

E' = (K/λ)

So, the quantity of energy per photon is inversely proportional to the wavelength of the light.

Hope this Helps!!!

According to the second law of thermodynamics, it is impossible for ____________. According to the second law of thermodynamics,
Tomtit [17]

Answer:

It's impossible for an ideal heat engine to have non-zero power.

Explanation:

Option A is incomplete and so it's possible.

Option B is possible

Option D is related to the first lae and has nothing to do with the second law.

Hence, the correct option is C.

The ideal engine follows a reversible cycle albeit an infinitely slow one. If the work is being done at this infinitely slow rate, the power of such an engine is zero.

We can also stat the second law of thermodynamics in this manner;

It is impossible to construct a cyclical heat engine whose sole effect is the continuous transfer of heat energy from a colder object to a hotter one.

This statement is known as second form or Clausius statement of the second law.

Thus, it is possible to construct a machine in which a heat flow from a colder to a hotter object is accompanied by another process, such as work input.

Match each type of wave to the way it moves. transverse wave longitudinal wave electromagnetic wave back and forth at right angl
marta [7]

Transverse wave = at right angles to the direction of the motion of the wave

in transverse wave medium particles will move perpendicular to the direction of motion of medium particles

they all are perpendicular to wave always

Longitudinal wave = back and forth in the direction of the motion of the wave

in longitudinal waves medium particles will move in the direction of wave and the motion is always in back and forth type

electromagnetic wave = alternating waves moving at right angles to each other

electromagnetic waves are combination of electric field and magnetic field which oscillates perpendicular to wave as well as they are perpendicular to each other
