1. What is the difference between longitudinal and transverse waves? Compare and contrast the direction of their movement, movement of a molecule through the completion of a cycle, and amplitude and wavelength measurements of each type of wave. 2. Suppose that a wave has a period of 0.03 second. What’s its frequency? Be sure to show the steps for your work.

3. Compare a wave that has a period of 0.03 second with a second wave that has a period of 1/4 second. Which wave has the greater frequency? Be sure to show the steps for your work.

4. If a wave has wavelength of 4.5 meters and a period of 0.07 second, what’s the velocity of the wave? Be sure to show the steps of your work.

5. Using the image below, identify the numbered parts of the wave.

Explanation:

1. The waves in which the partciles of medium vibrates in the same direction of propagation of wave, are called longitudinal waves.

The waves in which the partciles of medium vibrates in the perpendicular direction of propagation of wave, are called transverse waves.

2. Period, T = 0.03 s

The frequency is given by the reciprocal of the period.

the answer is to check all of them! they all apply well at least i think so!

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
