Describe the light-related discoveries of each of the following scientists, and state their significance:

a. Newton

b. Roentgen

c. Hertz

d. Bloch and Purcell

Interpretation Introduction

Interpretation:

The discoveries made by the given scientists related to light and their significance are to be described.

Concept Introduction:

The interaction of electromagnetic radiation with matter is called spectroscopy.

When an object is vibrating at the same natural frequency as that of a second object producing vibrational motion, this phenomenon is called resonance.

The distance between the two consecutive crests of a wave of light is called the wavelength of light.

Electromagnetic radiation with a certain wavelength is called light.

Explanation of Solution

a) Newton

Newton discovered that white light contains seven colors and can be split into its components when passed through a prism. These components of light can be passed through another prism to recombine and form white light again. This experiment shows that white light is a mixture of all visible colors.

b) Roentgen

Roentgen discovered X-rays. It is a type of electromagnetic radiation whose rays are used in detecting medical issues, such as fractured bones. It is also used in many others ways in medical sciences. More sensitive to soft tissues, can contrast more similar materials...
