Does an ambulance siren's pitch really change - what if the ambulance was stationary?
Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.
Is it true that Gene maps are produced by monitoring the frequency of crossing-over between genes?
It is true that gene maps are produced by monitoring the frequency of the crossing-over between genes. Their changes and adaptations are use in the construction of a gene map.
How are the different types of electromagnetic radiation similar?
all travel at the same speed, speed of light in a vacuum, 2.998x10^8 m/s they all have magnetic and electrical fiels perpendicular to one another along the propagation of the wave they all are transverse and so can be polarised they are all progressive waves and so can transfer energy they can all be reflected, refracted and diffracted and finally they all obey velocity=wavelength x frequency hope that helped
What is the radiation source for microwaves waves?
Microwave frequency radio waves are usually produced by a MAGNETRON.
What is the frequency of seeds produced by the tulsi plant?
From each Tulsi fruit two seeds are produced. Under subtropical conditions it flowers several times in the year and continuously produces seeds.
as you drive down the road you see and hear an approaching ambulance how is the frequency you hear different from being produced by the ambulance?
The wavelengths of the sound are compressed, making them shorter, and thus the frequency (and the pitch) higher. So the person in the oncoming car hears the siren operating at a higher pitch than the ambulance driver hears the same siren. This phenomenon is known as the Doppler effect.

If the frequency of the waves produced by a vibrating object increases how does the wavelength of the waves produced change?
The wavelength decreases. Frequency and wavelength are inversely related.
What determines the frequency of an electromagnetic wave?
The frequency of the source that produced the wave.
What is the maximum frequency that can be produced by a human?
3.4kHz
Number of waves produced per second?
This is known as the frequency of the wave and has the unit Hertz. Hertz is capitalized because it was named after a real person.The reciprocal of frequency is the period of the wave. That is the time in seconds for one wave to pass.
What is produced by vibrations that are multiples of the fundamental frequency?
overtones
How are frequency wave produced?
Please clarify what waves you are talking about. "Frequency waves" isn't very informative: every type of wave has a frequency.
Can a frequency produced by a guitar make objects in your house resonate?
Yes it can but the pitch of your frequency should be high
How does frequency of waves affect the pitch of the sound produced by vibrating objects?
The higher the frequency, the higher the pitch.
What is the tone produced by one vibration of a string?
fundamental frequency
