This and That
100
A mechanical wave's energy passes from particle to particle through a
medium
100
According to the Law of Reflection, if the angle of incidence is 35 degrees, then the angle of reflection must be
35 degrees.
100
The speed of sound depends on the
medium.
100
Electromagnetic waves can transfer energy with a(n)
medium.
100
In which of these mediums will sound travel the fastest in? water, air, space, bricks
bricks
200
Sound waves are a type of mechanical wave known as _____________ waves.
longitudinal/compressional
200
You can hear sound waves from around corners because of
diffraction.
200
The pitch of a sound that you hear depends on the sound wave's
frequency.
200
Which color on the visible light portion of the EM spectrum has the longest wavelengths?
Red
200
Ms. Gibson was wearing green tinted glasses. When she observed a traditional red and white candy cane, which colors did she see?
green and black
300
The distance from a point on a wave to a corresponding point on an adjacent wave is known as the
wavelength.
300
Light bends and slows down when traveling from air to glass because light waves ___________ when passing through denser mediums.
refract
300
The higher the amplitude, the _______________ the sound.
louder
300
Cell phones rely on electromagnetic radiation in which region on the electromagnetic spectrum?
microwaves
300
A material that allows all light waves to pass through is known as
transparent.
400
The part of the wave with the greatest amount of energy is the
amplitude
400
When waves meet resulting in a higher amplitude, we call this
constructive interference
400
Sounds travel slowest through which medium?
air
400
Which type of waves on the EM spectrum have the highest frequency?
gamma rays
400
_______________ materials reflect or absorb all light waves.
Opaque
500
The number of complete wavelengths in a given amount of time is a wave's
frequency.
500
When a wave moves through an opening in a barrier, it will _______________ and _______________. (don't name the wave behavior...say what the wave will do)
bend and spread out
500
Sound waves are compressed as an object moves toward an observer causing a high pitch then become rarefacted causing a low pitch after the passing the observer. The is known as the
Doppler Effect
500
The waves responsible for vitamin D production, causing cancer and sterilization of medical equipment are called
ultraviolet waves.
500
The speed of sound is 344 m/s when the air is 20 degrees Celcius. How far away is the source of the sound if it takes 8 seconds for the sound to reach you? (this is not a speed of sound calculation)
2752 m
