squid wave

what does a wave transfer?

• Molecules

• Energy

• Matter

• Force

As a transverse wave passes, the particles of the medium oscillate

• forward ans backward

• with different frequencies

• parallel to the direction of the wave travel

• perpendicular to the direction of travel of wave

As a longitudinal transverse wave passes, the particles of the medium oscillate

• forward ans backward

• with different frequencies

• parallel to the direction of the wave travel

• perpendicular to the direction of travel of wave

which of the following is an example of longitudinal waves?

• waves in ocean

• light waves in air

• a vibrating guitar string

• sound waves produces by a vibrating guitar string

• Amplitude : 0,02 cm , wavelength : 0,006 cm

• Amplitude: 0,003 cm, wavelength: 0,02 cm

• Amplitude: 0,003 cm, wavelength: 0,04 cm

• Amplitude: 0,006 cm, wavelength: 0,04 cm

A vibrating dipper of frequency 3 HZ produces water waves in a ripple tank. Which of the following is a possible wavelength and speed of a waves?

• wavelength: 3 cm speed= 1 cm/s

• wavelength: 3 cm speed= 6 cm/s

• wavelength: 4 cm speed= 12 cm/s

• wavelength: 15 cm speed= 5 cm/s

from the sea to the shore, the depth of the water decreases. Which of these statements describes waves coming in from the sea to the shore?

• speed increases and amplitude decreases

• speed increases and amplitude increases

• speed decreases and amplitude increases

• speed decreases and amplitude decreases

figure below shows a wave along a slinky with a frequency of 3 Hz and a wavelength of 0,3 m. what is the wave speed?

• 0,9 m/s

• 0,1 m/s

• 10 m/s

• 0,09 m/s

given that in a vacuum, the speed c and wavelength $\lambda$  of green light is  $3\times10^8\ \frac{m}{s}$  and 0,6  $\mu m$  respectively, calculate the frequency of the greenlight!

•  $5\times10^{14}\ Hz$  

•  $1,8\times10^2\ Hz$  

•  $1,8\times10^{14}\ Hz$  

The distance between two wave crests is called

• wavelength

• wave height

• throw

• period
