What else can I help you with?
What has the lowest frequency short wave or long wave radio?
Short wave frequency has a shorter wave length. Frequency is defined as number of cycles per second. If you have shorter waves (measure from peak to peak) you can get more of these packed into one second, so the frequency is higher.
What is a tuning fork and how is it used?
tuning fork steel instrument in the shape of a U with a short handle. When struck it produces an almost pure tone, retaining its pitch over a long period of time; thus it is a valuable aid in tuning musical instruments.
Does a large tuning fork make a higher note than a small tuning fork?
A large tuning fork makes a lower note and a smaller one makes a higher note. This is true with all instruments. Think about it: a string bass has much longer strings than a violin, and the bass is lower than the violin. In a piano or harp, the long strings produce the low notes and the short strings produce the high notes. Same with the length of pipes on a pipe organ. A low bassoon has a much longer length than a high little piccolo. Same with the brass instruments, a sousaphone or tuba has a much longer tube than a higher pitched trumpet.
What factor determines the pitch of a sound?
Pitch is the perceived frequency of sound. this may differ from the actual, measurable frequency of the sound because of overtones and harmonics, which when taken together the auditory part of the brain may perceive slightly differently.
What is the frequency fo radio waves in hertz?
From around 100kHz to around 500MHz. Below that, antennae need to be rather long to be efficient, above that the transmission range gets a bit short. But people have used much lower, and much higher frequencies, 40Hz - 20Gz and higher. The very high frequencies are often called microwave links.
What energy do waves with a short wavelength have?
It's possible it has low energy and high frequency.
Are the wavelengths of high frequency sounds short or long?
The wavelengths of high frequency sounds are short. This is because high frequency sounds have more cycles per second, resulting in shorter distances between peaks in the sound wave.
When a wave has high frequency is the wavelength short or long?
When a wave has high frequency, the wavelength is short. This is because frequency and wavelength are inversely proportional in waves. A higher frequency means more waves pass a given point in a given time, resulting in shorter wavelengths.
What has the lowest frequency short wave or long wave radio?
Short wave frequency has a shorter wave length. Frequency is defined as number of cycles per second. If you have shorter waves (measure from peak to peak) you can get more of these packed into one second, so the frequency is higher.
If i have a short strings it make a high pitch or low pitch?
Short strings tend to produce higher pitch sounds due to their higher natural frequency of vibration. This is because shorter strings have less mass per unit length compared to longer strings, resulting in a higher frequency of vibration and subsequently a higher pitch.
Does a high pitch sound have a low frequency?
No. High pitch = high frequency = short wave
Are microwaves higher in frequency than short wave radio?
Yes but has shorter wavelength than radiowaves.
Why do short wavelengths have more energy than long wavelengths?
Shorter wavelengths have more energy than longer wavelengths because they have higher frequency. According to the equation E = hf, where E is energy, h is Planck's constant, and f is frequency, energy is directly proportional to frequency. So, higher frequency (shorter wavelength) means higher energy.
Are high frequency waves close together or far apart?
High frequency waves are close together. This means that the waves have a short wavelength, and they oscillate rapidly. The shorter the wavelength, the higher the frequency of the wave.
Why does a wave with short wavelenth have a high frequency?
Wave velocity in general = frequency x wavelength As the velocity of the wave remains constant then frequency and wavelength are inversely related So as the wavelength becomes shorter then frequency becomes larger or higher
What travels faster short or long wavelength?
Short wavelengths travel faster than long wavelengths. This is because light travels at a constant speed, and since wavelength is inversely related to frequency (shorter wavelength means higher frequency), shorter wavelengths have higher frequencies and thus travel faster.
Why are the metal prongs of a plug sealed in plastic and rubber?
The metal prongs of a plug are sealed in plastic and rubber for insulation and safety purposes. This helps to prevent electrical shocks and short circuits by providing a protective barrier between the conductive metal prongs and the user.
