Electromagnetic
or Transverse​

Are formed where bumps from two surfaces come into contact ?

If frequency goes up, what happens to wavelength? does it get shorter or longer?

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
