Two Wave types: Longitude and Transverse Waves
Description of Transverse:
Explanation of how waves are created:
Why waves are important:
We need to understand waves becasue they are abundant in our life every day. We need to be able to understand them to put them to good use.
An example of both longitudal and transverse waves are earthquakes: Earthquakes result in the formation of seismic waves. Seismic waves are waves of energy that are transported through the earth and over its surface by means of both transverse and longitudinal waves.
Description of longitudal waves:
Part 2 Measurement of Spherical Waves
Wave Length
x/2.5=1/1
1x=2.5
x=2.5 λ
Wave Frequency
The amount of waves that passed the 2.5 centimeter tape is 39 times. The video of the Spherical wave was 8 seconds.
Frequency is 39/8= 4.9 hertz.
Wave Speed
22 waves passed the 2.5 centimeters of tape and the video was 10 seconds long.
Frequency is 22/10= 2.2 hertz
Measurement of Plane Waves : Wave Length
x/2.5=1/0.4
0.4x=2.5
x=6.25 λ
Wave Frequency
22 waves passed the 2.5 centimeters of tape and the video was 10 seconds long.
Frequency is 22/10= 2.2 hertz
Wave Speed
The formula for speed of a wave is v=λ*hertz
The wavelength is 6.25 and frequency is 2.2 so when multiplied together the speed is 13.75 cm/s
Part 3
Wave Interference
Occurs when two waves meet each other while traveling at the same medium. The interference of the waves causes the medium to take on a shape that results the net effect from the two individual waves upon particles of the medium.
Dual Pin
Dual pin is two individual pins connected to the vibrater that causes two waves to travel.
Double Slit
Two blocks that have a gap in between the ripple tank causing the wave to form two waves that travel.
Simarality
They both form two waves that goes into the circle.
Difference
Dual pin has a complete full shape circle
Double slit is the shape of an oval.
PART 4
Wave reflection #1 is at 45 Degrees:
The angle of incidence is 45 Degrees
The angle of reflection is 45 Degrees
Wave reflection #2 is at 90 Degrees:
The angle of incidence is 90 Degrees
The angle of reflection is 90 Degrees
Wave reflection #3 is 30 Degrees:
Angle of incidence if 30 Degrees
Angle of reflection is 30 Degrees
Law of Reflection
Part five
Wave diffraction defined:
Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture. The bending and spreading of a wave, such as a light wave, around the edge of an object.
- Wave diffractions can occur in many ways. Ocean and sound waves both diffract with different obstacles. That's why you can still hear someone when something else is in the way.
