Chapter 3.1, Problem 3.4YT

(a)

Interpretation Introduction

Interpretation:

The color that has longest wavelength and highest frequency has to be identified.

Concept-Introduction:

Wavelength: The distance between successive peaks in a wave and measured in units of length.

Frequency: The number of waves passed a point in a certain amount of time.

Relation between wavelength and frequency:

$\text{Frequency}\left(\text{ν}\right)\text{=}\frac{\text{speed}\text{of}\text{light}\left(\text{c}\right)}{\text{wavelength}\left(\text{λ}\right)}$

Where, c is constant, the value of c is $\left(\text{3}{\text{.00×10}}^{\text{8}}\text{m/s}\right)$ and represents the maximum velocity that light is able to travel through air.

(b)

Interpretation Introduction

Interpretation:

The given wavelength unit has to be expressed in meters.

Concept-Introduction:

Conversion of meter into nanometer (m to nm): $\text{1 nm}\text{=}{\text{1×10}}^{\text{-9}}\text{m}$
