Waves have a peculiar property: they can cancel. Give examples of cancellation for sound, light, water, and earthquakes. Explain why cancellation is so difficult to observe for light.
Homework Answers
light has partical nature along with wave nature, so particles
don't cancel each other so the waves too. but, happens rarely

We are working on the wave model of light. The idea that waves can move around on the surface of a swimming pool or a pond is obvious, partly because you can see the surface of water and the waves have large enough wavelength so you can easily see it. We can see light, but the wavelength is very very short, much shorter than our unaided eyes can see. For example, our eyes are most sensitive to green light. Green...

and 4 and filling out the table
Lab 12. Sound Waves and Beats Introduction Sound waves consist of a series of air pressure variations. A Microphone diaphragm records these variations by moving in response to the pressure changes. The diaphragm motion is then converted to an electrical signal. Using a Microphone and an interface, you can explore the properties of common sounds. The first property you will measure is the period, or the time for...

4) Interference and Diffraction Phenomena (10 points) (a) In a single slit diffraction experiment with a screen far away from the slit, with waves of wavelength 1, there will be no intensity minima if the slit becomes too small compared to the wavelength. What is the minimum slit width (in terms of ) for which no intensity minimum occurs? (Note: if there is no minimum, the screen looks essentially fully illuminated. Think what condition that puts on the angle of...

Examples: Example 1-Runtime Polymorphism: Lets say we have a class Animal that has a method sound(). Since this is a generic class so we can't give it a implementation like: Roar, Meow, Oink etc. We had to give a generic message public class Animal public void sound System.out.println("Animal is making a sound"); Now lets say we a subclass of Animal class. Horse that extends Animal class. We can provide the implementation to the same method like this: class Horse extends...
