<u>Answer:</u> The frequency of the light is
<u>Explanation:</u>
The equation used to calculate the energy for a transition, we use the equation:
where,
n = principal energy level
Calculating the energy difference:
To calculate the energy of the light for a given frequency, we use the equation given by Planck, which is:
where,
E = energy of the light =
h = Planck's constant =
= frequency of the light = ?
Putting values in above equation, we get:
Hence, the frequency of the light is

Explanation:
A property that does no change the chemical composition of a substance are known as physical properties.
For example, mass, volume, size etc are all physical properties.
Whereas a property that changes the chemical composition of a substance are known as chemical properties.
For example, reactivity, toxicity etc are all chemical properties.
Therefore, identifying the given statements as follows.
- The various components of a mixture do not combine chemically - physical property.
- Chemical properties can only be observed during a chemical reaction - chemical property.
- The rusting of iron is a chemical reaction - chemical property.
- Melting and boiling points are physical properties - physical property.
