When the nanocrystalline semiconductor samples provided in case study are irradiated with violet light, you should observe that different samples emit different colors of light. Explain how the trend in the observed emitted colors (from violet towards red) is related to a trend in the band gap energies of these samples.

Due to the different lattice arrangement of nanocrystalline semiconductors, they will be able to emit different colors of light.

Explanation:

An essential feature in nanocrystalline semiconductor samples is that they may not have the same or in some cases similar structures. This characteristic is due to the fact that nanocrystals do not grow equally, presenting different shapes. Nanocrystals with uneven shapes may absorb light of a certain wavelength, but due to their uneven characteristics, the light emitted may be of a different wavelength.

The type of energy that is ar work when blinds are being raised or lowered is potential energy. because potential energy is the energy stored in an object due to its vertical position, the main cause of the potential energy is the acceleration due to gravity. so that is why its formual is PE = mgh
where m is the mass, g is the acceleration due to gravity and h is the height
