The basic properties of transverse waves are: Amplitude Time Period Frequency Phase Wavelength Crest Trough
A propeller works by converting the rotation of the engine into horizontal thrust similar to a fan. The blades push the air backwards creating acceleration, and create a difference in pressure between the forward and rear surface adding to the movement. The above is, of course true for a boat propeller. For an airplane propeller Bernoulli's pincipal is involved. Bernoulli's principle states that the greater the speed of a fluid, the less the lateral pressure. So the propeller uses the same deal as the wing.
Yes definitely. Reciprocal of wavelength is proportional to frequency as lambda = v /frequency. v - the speed of the wave. The frequency has to be greater than some minimum value known to be the threshold frequency. As frequency increases then kinetic energy of the photo electron also increases. If the frequency of the incident photon is less than the threshold and however higher the intensity, there is no chance of ejection of photo electron right from the surface of the substance. So no photo electric emission is possible.
The greatest wavelength of radiation for a specified surface for the emission of electrons.
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
The frequency of the laser in the alcohol will be 680nm and the speed of light as always, is 299,792,458 meters per second. Why did you need to ask this?
At low frequency, a large diameter speaker moves with the entire surface area in phase. But at a specific frequency, dependent on the speed of sound in the membrane material and the diameter, the surface closest to the drive point and the outer edges of the surface starts to move out of phase. The speaker wobbles, creating distortion and decreased sonic output. So a large area speaker is by this reason less well suited for reproducing high frequency signals. Also, a large speaker is heavy, and is harder to accelerate. This also limits the high frequency reproduction. Adversely, a small area speaker needs to move far, have a high amplitude, to reproduce low frequency signals, creating Doppler distortion and unlinear reproduction. One way to solve these problems is to divide the signal between two or more drivers of different sizes.
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.

The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
well, right now it is believed that light travels in waves and is made up of massless particles called photons. these waves propagate at a constant speed, 3*10^8 m/s. Nothing can travel faster than this speed and nothing can travel the speed of light if it is not massless (so sorry, no hyperspace travel yet) while light always travels at the same speed, the frequency and wavelength of these propagating waves are not always the same. In the visible spectrum, the highest frequency waves are viewed as purple and the lowest frequency waves are red. The faster the frequency, the more energetic the wave. the frequency, wavelength, and speed of light are related to each other by this equation: speed of light=wavelength*frequency when dealing with the electromagnetic spectrum it is often easier to refer to light as electromagnetic radiation, especially when dealing with very high and very low frequencies that result in infrared, ultraviolet, radio, x-ray, etc. there is a lot of information out there about light, I'm just scratching the surface :-)
