Question 3

• The electromagnetic spectrum is a continuum of wavelengths of electromagnetic radiation.

Answer 3

• The electromagnetic spectrum is a continuum of wavelengths of electromagnetic radiation.

Question 4

A quantum is an indivisible amount of something,
such as light, energy, or matter. For example, the
mass of sucrose is quantized. The smallest
increment of mass that can be added or removed
from a sample of sucrose is one molecule—
anything less is no longer sucrose.

Question 5

Light has wave properties, including wavelength,
amplitude, velocity, frequency, and period.
The wavelength (λ) is the distance between one
wave maximum and the next. The amplitude (A) is
the height of the wave, and the velocity (v) is the
rate at which a wave is propagating in a given
direction. The frequency (ν) is the number of wave
peaks that pass a point per unit time, and the period
is the time interval between peaks of a wave.
Wavelength (λ), frequency (ν), and velocity (v) are
related by the equation v = ν • λ. For light, the
velocity is a constant, c = 3.00 x 108
m/s.

Question 6

The electromagnetic spectrum is a continuum of
wavelengths of electromagnetic radiation. Visible
light is a small subset of this spectrum, which also
includes gamma radiation, x rays, ultraviolet
radiation, infrared radiation, microwaves, and
radio waves.
