Waves
What happens to the frequency of a wave as the wavelength gets longer?
The frequency gets smaller
What type of wave is light?
electromagnetic
you watch 16 ocean waves go by in 48 seconds? What is the period and frequency
the period is 3 sec. The frequency is .33 hz
how do you get the frequency with only the period? what is the equation
f=1/t or t=1/f
what are the main factors that affect the speed of sound?
compressed ability, stiffness, density, and temperature
What type of wave carries energy perpendicular to the direction of the medium?
Transverse
finish the sentence! light bounces off a mirror,
at the same angle it hits the mirror.
sound is what type of wave?
Longitudinal and machanical
a sound wave has 1500 meters per second and has a wavelength of 5 meters. what is the frequency? what is the equation don't worry about answer
1500/5 = f
what are the properties of a wave?
Wavelength, Amplitude, Frequency
The pitch in a sound wave is based on the ______ of the wave.
Frequency
What type of EM radiation has the highest energy?
Gamma Radiation
As the train approaches him, the sound waves are_________ which causes the pitch to be ________.
compressed. higher.
what is the equation between the speed of the wave?
wavelength times frequency equals speed of wave.
waves move;not______
energy not matter
When waves energy increases, its________increases.
amplitude
light travels in a _______ line
straight
the higher the ______ the higher the ________
pitch. frequency.
or
sound. amplitude.
Amplitude
what wave goes under ground?
seismic waves
What causes a wave to refract?
change in its speed
the colors that make up white light are called what?
visible spectrum
what are the units for sound
decibuls
What wave can't go through vacuum?

true or false! concave mirrors flip the image
True
