# Ripple Tank Project

## Description of Transverse:

A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Transverse waves cannot propagate in a gas or a liquid.

## Explanation of how waves are created:

waves are created by a vibration in time and space which may cause the surrounding medium to vibrate

## 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.

Longitudal waves are used everyday and examples are sound waves, speaker, and your ear receiving a sound wave. We see transverse waves everyday because light is an example, and so is a ripple in a pond or on a string. Other examples include gamma rays, x-rays, micro waves, and more

## Description of longitudal waves:

A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.

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

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

## 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.

## Wave reflection #1 is at 45 Degrees:

The angle of incidence is 45 Degrees

The angle of reflection is 45 Degrees

45 Degrees

## Wave reflection #2 is at 90 Degrees:

The angle of incidence is 90 Degrees

The angle of reflection is 90 Degrees

90 Degrees

## Wave reflection #3 is 30 Degrees:

Angle of incidence if 30 Degrees

Angle of reflection is 30 Degrees

30 Degrees

## Law of Reflection

When light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence

## Wave diffraction defined:

1. 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.

2. 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.

## Observation Stated

The larger the wavelength the larger the diffraction
