Explanation:
holes are left due to space left out the migrating electrons. they are positive charge carriers. if the electron moves in one direction, the holes appear to move in the opposite direction.
Answer:
The frequency of the photon is 7.41*10¹⁶ Hz
Explanation:
Planck states that light is made up of photons, whose energy is directly proportional to the frequency of radiation, according to a constant of proportionality, h, which is called Planck's constant. This is expressed by:
E = h*v
where E is the energy, h the Planck constant (whose value is 6.63*10⁻³⁴ J.s) and v the frequency (Hz or s⁻¹).
So the frequency will be:

Being E= 4.91*10⁻¹⁷ J and replacing:

You can get:
v= 7.41*10¹⁶
= 7.41*10¹⁶ Hz
<u><em>The frequency of the photon is 7.41*10¹⁶ Hz</em></u>
