What are the two types of waves

Answer 1

-transverse (ripples on water )

Question 2

What is amplitude

Answer 2

Maximum displacement of a point on the wave from its undisturbed position

Question 3

What is the wavelength

Answer 3

Distance between the same point on two adjacent waves (between the trough of one wave and the trough of the wave next to it )

Question 4

What is the trough and crest

Answer 4

Trough = lowest point
Crest = highest point

Question 5

What is frequency of waves

Answer 5

-Number of complete waves passing a certain point per second
-measured in hertz
-1 hz is one wave per second

Question 6

What do waves do

Answer 6

-transfer energy in the direction they are travelling
-when waves travel through a medium, the particles of the medium oscillate and transfer energy between each other

Question 7
