![]() Trough - it is just the opposite of crest. Whereas the transverse waves are formed at the surface.Ĭrest - a point on the medium which has the maximum amount of positive or upward displacement from the position of the rest, that is known as the crest of the wave. The longitudinal motion or the longitudinal wave are found when the energy has to be transmitted within the medium. Depending on the type of motion two forms of waves are classified, the first one is a longitudinal wave and the second is a Transverse wave. We know that the energy of the particles in motion is transmitted in the form of waves. The pattern of disturbances is of two types or in other words the formation of waves is done in two different methods. With the combined motions, it results in moving forward in the alternating region of compression and rarefaction towards the propagation’s direction. ![]() The seismic waves which are primary p, are also longitudinal.Īll the particles in the longitudinal wave, vibrates to its rest position which is normal and with the axis of propagation, and all the particles that participate in the wave motion behaves in the same way, except in phase of vibration, there is a case of progressive change that means every particle finishes its cycle of reaction at a time that is later. Moving of the sound through air results in compressing the gas in the direction where sound waves are travelling while they vibrate back and forth. The coil of the spring has a point that moves with the wave and returns from the same path, while returning it passes from the neutral position and then again reverses its motion. When you compress one end of the coiled spring and release it, it experiences a wave of compression which travels to the length of it, stretching follows it. In as few words as possible describe the 4 phenomenon all waves have.A wave that consists of a vibration or any periodic disturbance which happens in the same direction like the advance of the wave.How many nodes and antinodes does this standing wave have?.What is true about the wavelength of a standing wave with a lower frequency?.Draw and label (node and antinode) of a standing wave with 3 nodes and 2 antinodes.A standing waves reflection must be the same _.Finish off table by drawing the waves interacting during and after their interference.How are they similar? How are they different? Compare and contrast constructive and destructive interference. ![]() Why can waves travel through each other and not collide?.Is light bending toward or away from the normal line (on the air side) when you look at a fish in water where light travels slower?.If a ray of light were traveling from Air to water at a 30° angle of incidence, would its angle of refraction be more than 30°, less than 30°, or equal to 30° on the water side?.If an incident wave has an angle of incidence of 35°, what would be the angle of reflection?.Draw and label a diagram for reflection of a wave.Describe what happens to the wave after it bounces off a fixed boundary. ![]()
