A
distance travelled by a wave in a second
2

Formula of speed
A
v=f x wavelength
3
Q
What is amplitude
A
Maximum displacement of the wave from the rest position
4
Q
What does it mean to be in phase
A
two waves moving in same direction and having same displacement from their rest position
4
Q
What is wavefront
A
imaginary line on wave that joins all adjacent points that are in phase
4
Q
What are transverse waves
A
travel in perpendicular to the vibration of particles
5
Q
What are longitudinal waves
A
waves that travel in a direction parallel to vibration of particles.

A
Speed of light decrease in optically denser medium
speed of sound increase in optically denser medium
freq does not change in medium
