Waves - SL
-
Frequency
-
the amount of full waves completed per second, measured in Hz. Frequency and period have an inverse relationship.

Interference
A standing wave pattern is an interference phenomenon. It is formed as the result of the perfectly timed interference of two waves passing through the same medium.
-
-
Boundary Conditions
The nature of the end points of strings and pipes affects the frequency of the standing
waves and is referred to as the boundary condition.

Bend

Refractive index measures the effect a medium has on light. Greater the refractive index, the greater the change in speed and direction. The refractive index of a medium is always the same whether light moves from air into medium or vice versa.
-
Bounce
The angle between the incident
wave and the normal is equal to the angle between the reflected wave and the normal.
-
The angle that the incident light makes with the normal is equal to the angle made by the reflected light. The transmitted light is said to be bent or refracted at the boundary between the air and the glass. This is due to the speed of light being less in glass than air. It will bend towards the normal.

Sinlge Slit
-
As width of slit decreases, distance between min and max points increases
-
All waves are similar...
-
When waves meet, the resultant displacement is the vector sum of the displacement of the two waves.
When waves completely overlap, they form super-crests or super-troughs. Interference has greater displacement in medium.

-
Light is brighter when you are closer, and dimmer when you are far away

-
The light energy that is twice as far from the source is 4 spread over 4 times the area, meaning the intensity in 1/4 of its original (inverse square law)
