We need the frequency of the photon, it is v = c/ λ
Where c is 3 x 10^8 ms^-1 and λ
is the wave length
We also need the expression of
connecting frequency to energy of photon
which is E = hv where h is Planck’s
constant
Combining the two equations
will give us:
E = h x c/λ
Inserting the values, we will
have:
E = 6.626 x 10^-34 x 3 x 10^8 /
0.126
E = 1.578 x 10^ -24 J
<h2>Answer: True
</h2>
Lenz's law, formulated by the physicist Heinrich Lenz in 1834, relates changes produced in the electric field by a conductor (a loop of wire, for example) with the property of varying the magnetic flux, and states that:
<em>The voltages applied to a conductor generate an electro-motive force whose magnetic field opposes any variation of the original current that produced it.
</em>
<em>
</em>
In other words:
<em></em>
<em>the induced electricity will be in a direction that opposes the variation of the magnetic flux that produced it </em>
This is due the polarity of the induced voltage and it is an infallible consequence of the principle of conservation of energy.
The answer is Meaningful Learning.
Meaningful learning refers to the concept that an individual
fully understood the learned knowledge, and that he or she knows the specific
fact that relates to other stored facts.
