Use the following information to answer the next question.
in ultrasound technology, sound waves with a frequency of 3.02 x 10° hz
and a wavelength of 5.13 x 10-4 m pass through the body. reflected waves
are analyzed by a computer to produce an image.
the speed of the sound waves passing through the body is
a.
b.
c.
d.
1.70 x 10-10 m/s
1.55 x 103 m/s
3.00 x 108 m/s
5.89 x 10 m/s

Which type of microscope would allow the viewer to see ribosomes inside a cell?

Which of these is constant for all types of electromagnetic radiation in a vacuum? select one: a. wavelength b. frequency c. photon energy d. amplitude e. velocity

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
