Waves Vibrations and Oscillations

When you hit it, the triangle vibrates, and the air around it vibrates. The air particles closest to it vibrates, then the air particles next to the first ones start vibrating as well and so on, so it reaches your ear.

If the dept of the water is high the wave is basically moving water over water as a result, that the friction between the waves is less. Due to those facts the wave speed in deep water is greater than in shallow water. In shallow water the waves in the water have a frictional drag at the bottom of the tray. Therefore, the waves speed it lower than in deeper water.

Oh, dude, you're looking for an appliance that uses small sound waves? That would be a microwave! It heats up your leftovers with those tiny sound waves, like a little culinary concert in your kitchen. Just make sure you don't accidentally turn your burrito into a rock concert, unless you're into that kind of thing.

Well, isn't that a happy little question! In simple harmonic motion, the magnitude of the acceleration is greatest when the object is at its maximum displacement from the equilibrium position. Just like painting a beautiful landscape, understanding the peaks and valleys of motion can help us appreciate the beauty of physics.

The energy is being transported. In the case of a light wave, it is electromagnetic energy. In the case of a sound wave, it is sound energy. (The matter is not being transported, only the energy.)

Using a pendulum as an example: a pendulum swings from left to right (first swing) and then swings back again right to left (second swing). A complete oscillation is composed of both swings.

Echo is an example of constructive interference. Constructive interference occurs when two waves combine to produce a wave with a larger amplitude. In the case of an echo, the original sound wave and its reflection combine to create a louder sound. Destructive interference, on the other hand, occurs when two waves combine to produce a wave with a smaller amplitude.

There is one value of amplitude in one wavelength of a wave. The amplitude of a wave is related to the energy of the wave - waves with higher amplitudes carry more energy than waves with lower amplitudes.

Keeping the bob of a simple pendulum near the floor reduces the potential energy of the system, which in turn decreases the amplitude of the pendulum's swing. This can help prevent the pendulum from swinging too wildly and potentially causing damage or injury. Additionally, having the bob closer to the floor reduces the distance it needs to fall, which can minimize the impact force when the pendulum reaches its lowest point.

Well, isn't that a happy little question! Increasing the amplitude of a wave doesn't actually affect the wavelength itself. The wavelength is the distance between two consecutive points in a wave that are in the same phase, like two peaks or two troughs. So, no matter how tall or short the wave is, the wavelength stays the same, just dancing along peacefully.

yes

A pendulum is a piece of string attached to a 20 g mass that if you double the length it will take twice as long to swing.

Yes.

That one.

Waves travel in groups due to the phenomenon known as wave grouping or wave packet formation, which occurs when individual waves with similar frequencies and speeds combine. This interaction can amplify certain waves while minimizing others, leading to the distinct grouping effect. Additionally, factors like wind patterns, currents, and the seabed's topography can influence how waves interact, reinforcing the tendency for waves to travel in clusters. Consequently, these groups can create more powerful and organized wave patterns, which are more efficient at transferring energy.

Since, frequency, f = c / λ

Then, λ = 405 x 10-6 cm = 4.05 x 10-10 m

Speed of light c = 299,792,458 m/s

Therefore, frequency f = 299,792,458 m/s / 4.05 x 10-10 m = 740,228,291,358,024,691 Hz = 7.40 x 1017 Hertz.

It is an electrical oscillator which uses two transistors or vacuum tubes and a LC circuit.

The two transistors are connected as a two stage amplifier, both stages are inverting. the output of the second is coupled to the input of the first by a tuned circuit. Provided the amplifiers have enough gain, the circuit will oscillate, because the two amplifiers each give 180 degree phase shift, so the output is in phase iwth the input, so the oscillations build, until they are limited in amplitude by gain compression.

c = λν
3x10^8 m/s = 310x10^-9 m (ν)
ν = 9.68x10^14 Hz

The product of frequency and wavelength in a wave is the speed of the wave, which remains constant in a given medium. This relationship is summarized by the wave equation: speed = frequency x wavelength. This means that as one of the values (frequency or wavelength) increases, the other value must decrease to maintain a constant wave speed.

It refers to how small a signal a receiver can process. All receivers have a "minimum discernable signal" (MDS). Below that level, background noise (static) will be all that you can hear. Your car radio may not process a 1,000 watt signal from a station 1,000 miles away but NASA has receivers that can process 0.1 watt signals from millions of miles away. A lot of it has to do with filtering and the number of amplification stages involved.
