review questions part 1-2

refraction occurs when a wave changes its __________ as it pass through a different medium

• color

• frequency

• intensity

• speed

houses with carpet are much quiater than houses with tile hardwood floors because of sound wave

• absorption

• diffraction

• reflection

• refaction

which is an example of a compressional wave?

• x-ray

• gamma ray

• sound wave

• water wave

increasing the amplitude of a sound wave will make it

• lounder

• have a higher pich

• travel faster

• produce beats

ocean waves crash on the beach at a velocity of 3.5 m/s if the distance between the crests of each wave is 4m find the frequency of the waves

• 0.88 HZ

• 1.14 HZ

• 0.0088 HZ

• 14.0 HZ

the picture to the left shows which wave behavior

• absorption

• reflection

• diffraction

• refraction

an echo is an example of sound wave

• absorption

• reflection

• diffraction

what is velocity of a wave having a frequency of 25 HZ and a wavelength of 10 m?

• 250 m/s

• 2.5 m/s

• 35m/s

• 0.4m/s

a glass prism is able to bend light because

• light is refracted as it enter a different medium

• the prism creates destructive interference

• energy is diffracted when is encounters an obstacle

• the glass and the light's wavelength create resonance
