Back (Answer)

Electromagnetic Radiation

#2
Front (Question)

is the highest point while trough is the lowest point

Back (Answer)

Crest or peak

#3
Front (Question)

is the distance of two peaks/crest or troughs when light travels in a wavelike manner

Back (Answer)

Wavelength

#4
Front (Question)

Units:

Back (Answer)

Angstrom (A)Millimicrons (mu) Nanometer (nm)

#5
Front (Question)

Conversion factors:

Back (Answer)

1 nm = 10 A; 1 nm = 1 mu; 1 A = 10 mu

#6
Front (Question)

is the number of waves that pass an observation point in a unit of time

Back (Answer)

Frequency

#7
Front (Question)

is the distance between two adjacent peak and trough

Back (Answer)

Amplitude

#8
Front (Question)

is inversely proportional to the frequency of the light wave

Back (Answer)

Wavelength

#9
Front (Question)

is inversely proportional to the wavelength of light

Back (Answer)

Energy

#10
Front (Question)

 The shorter the wavelength,

Back (Answer)

the larger number of photons will be contained in a given distance

#11
Front (Question)

 More photons represents more energy, hence,

Back (Answer)

shorter wavelengths represent higher energy

#12
Front (Question)

 Wavelength or frequency of the electromagnetic waves are perceived as

Back (Answer)

color or hue

#13
Front (Question)

shorter wavelength = high frequency color

Back (Answer)

bluish colors

#14
Front (Question)

long wavelength = low frequency colors

Back (Answer)

reddish color

#15
Front (Question)

 Height or amplitude of the electromagnetic waves are perceived as

Back (Answer)

intensity or brightness

#16
Front (Question)

great amplitude=

Back (Answer)

bright colors

#17
Front (Question)

small amplitude =

Back (Answer)

dull colors
