Question

State the energy changes that takes place in the following case:

Exposure of photographic film in sunlight.

Answer 1

Sunlight has light energy that is converted into chemical energy.

Energy change:

$$\begin{gathered} Lightenergy\to Chemicalenergy \\ \left(Sunlight\right)\left(film\right) \end{gathered}$$

Answer:

Hence the energy changes that take place when a photographic film is exposed to sunlight are from light energy to chemical energy.
