Chapter 7, Problem 58E

Interpretation Introduction

Interpretation:

The difference between two pictures is to be explained on the basis of the brightness of the objects.

Concept Introduction:

The color of any substance depends on the color of the light absorbed by the molecules or atoms that compose the substance and the color that it reflects back.

Light has particle and wave properties; hence it has dual characteristics.

Wavelength of light determines its color and energy.

Electromagnetic radiation ranges in wavelength from the gamma waves region to the radio waves region.

In the visible region, the white light contains spectrum of wavelength ranging from $400\text{ nm}-780\text{ nm}$.

Infrared radiation has a wavelength longer than the visible light ranging from $700\text{ nm}-1\text{ mm}$.
