Which of these electromagentic waves has the shortest wavelength?
X-rays
When visible light is incident upon clear glass, atoms in the glass
are forced into vibration
Sunburns are produced by
ultraviolet light
The size of the pupil of your eye depends on
your mood
the brightness of light in the room
Which of the following can not travel a vacuum?
a sound wave
A pair of sunglasses and a pair of reading glasses are left in the sunlight. The hotter glasses would be the
sunglasses
The color of an opaque object is the same as the light that is
reflected
What color light is transmitted by a piece of blue glass?
blue
Complimentary colors are two colors that
produce white light when added together
Different colors of light correspond to different light
frequencies
A mixture of cyan and yellow pigments appears
green
The sky is blue because air molecules in the sky act as tiny
resonators which scatter blue light
Red sunsets are due to lower frequencies of light that
survive being scattered in the air
The greenish blue of water is evidence for the
absorption of red light
According to Huygen's Principle, every point on a wave
behaves as a source of new waves
Polarization is a property of
transverse waves
Light will not pass through a pair of polaroids when their aces are
perpendicular
Monochromatic light is light of a single
wavelength
frequency
color
Light from a lit match comes from
electrons
Light is emitted when an electron
makes a transition to a lower energy level
Compared to the energy put into a laser, the energy of the laser beam is
less
Light from a laser is
monochromatic
in phase
coherent
A watch dial that continues to glow after a week in the dark is almost certainly
radioactive
Infrared waves are often called heat waves because they
induce resonance in molecules and increase internal energy in a substance
In the process of fluorescence, part of the input energy immediately
becomes internal energy and the rest lower frequency light
