How does destructive interference affect the amplitude of a wave?
Destructive interference affect the amplitude of a wave because two identical waves with similar amplitude and wavelength, arrive in anti phase, leading to a zero displacement.
What is frequency of a wavelengh?
Frequency and wavelength are two characteristics of waves and are not characteristics of each other. Wavelength is the length of a wave from peak to peak or trough to trough. Frequency is how often the wave peaks arrive.
What are the necessary conditions of interference of light waves?
They must arrive 180 degrees out of phase. (Waves must be of the same frequency.) In a situation where two identical waves (amplitude and frequency) arrive 180 degrees out of phase, the crests meet the troughs and the troughs meet the crests. The waves effectively "cancel each other out" here, or, as a mechanic might say, the vector sums of the waves total zero. If the waves are not equal in amplitude (but are in frequency), they will at least sum to a minimum energy. Put two speakers 10 to 20 feet apart and point them toward each other. Hook everything up "normally" and walk between the speakers. Then reverse the speakers wires to one speaker. (No, it won't hurt the speakers or the audio system.) Walk between them again. Biiiiiiig difference. Note that this experiment is a 3-dimentional test. Study a bit on the 2-dimentional problem before moving to 3-D. (It's just that this experiment is fun! It makes the phenomenon so real to the observer.) This a problem in what is sometimes called two-point source interference. Use the link to visit a site where drawings are posted. A picture is probably worth a thousand words in this case.
What does the Doppler radar measure?
A narrow microwave signal is directed at the moving vehicle at a known frequency, due to its motion the reflected signal will arrive back at the radar at a different frequency, an algorithm in the radar processor converts this difference to give the vehicles speed. Presumably the angle between the cop and the speeder will have to be taken into account as well.
What is the Relation between amplitude and velocity of wave?
In most media and in most cases, there is no relationship. Amplitude and velocity are completely independent of each other. In the case of sound, that's the only way you can listen to a live band or orchestra. If the speed of the sound depended on the amplitude, then the sounds of the loud and soft instruments would reach you at different times, and chords would get all smeared out. That's also a very interesting thing to think about in the case of radio communication. A radio signal can be seen as a package of components with many different frequencies and amplitudes; they all go together to describe the sound of the program (or the details of the TV picture). If the higher- and lower-amplitude components came to you at different speeds, then again, the details would get all "smeared out" in time. A complicated sound or picture that left the studio at one instant would arrive at your house spread out over some time, and the sound or picture would be totally torn up.
What happens to the frame of a seismograph when seismic waves arrive?
It moves with the same frequency and amplitude as the seismic waves, while the large mass suspended within it is damped from these oscillations due to it's own inertia. The relative movement between this stationary mass and the frame can then be recorded.

How many hertz are in the sun?
Frequency, in Hertz is the inverse of Period. Given that our sun poofs and puffs once every 11 years, we can state that frequency is the inverse of that Period. You are welcome to figure out how many seconds there are in this period -- and from there arrive at the frequency you seek.

As soon as you arrive what sentence structure is this?
"As soon as" is a conjunction that shows something that happens immediately (that is, at the moment another action is completed; in this case, as soon as you arrive, _____ will take place).
In french how do say whatever happens i will be waiting for you?
Tryquoi qu'il arrive je serai là pour toi(no matter what happens, I shall be there for you).
What happens if you miss a step when solving a rational equations?
Presumably you'll arrive at the wrong solution.
