Two sinusoidal waves traveling in opposite directions interfere to produce a standing wave with the wave function y = (2.00) sin(0.500x) cos(300t) where x and y are in meters and t is in seconds. (a) determine the wavelength of the interfering waves. m (b) what is the frequency of the interfering wave? hz (c) find the speed of the interfering waves.

Part a)

Part b)

Part c)

Explanation:

Part a)

As we know that angular wave number is given as

Part b)

As we know that angular frequency is given as

Part c)

Speed of the wave is given as

so we have

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
