(a)

Interpretation Introduction

**Interpretation:** The wavelength of cell phone signal has to be calculated.

**Concept introduction:**

The frequency of the light is inversely proportional to its wavelength.

(b)

Interpretation Introduction

**Interpretation:** The energy per mole of photons of cell phone signal has to be calculated.

**Concept introduction:**

Planck’s equation,

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.

(c)

Interpretation Introduction

**Interpretation:** The energy of violet light is to be compared with

**Concept introduction:**

- Planck’s equation,

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.

- The frequency of the light is inversely proportional to its wavelength.

(d)

Interpretation Introduction

**Interpretation:** The energy difference in violet light and cell phone signal with

**Concept introduction:**

Planck’s equation,

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.
