Answer:

Explanation:
The number of oscillation per unit time is called frequency of a wave while the distance between two consecutive crests and the trough is called its wavelength.
The wavelength of a wave is given by :

If frequency is doubled, f' = 2f




So, when the frequency is doubled the wavelength of a wave on the string becomes half.
Answer:
Wavelength
Explanation:
Wavelength is the distance between two corresponding consecutive phases of a waveform. It is usually represented by λ in the mathematical expressions.
A continuous propagating wave repeats its wavelength over the distance.
A wave has crest and trough with respect to time and space.
Wave is defined as a disturbance of any parameter repeated in a cyclic manner over the given time.
The element number 17 is associate with Chrlorine which has 17 protons and 18 neutrons.
Answer:
83.74 cm
Explanation:
The air column over water level will act as vibrating air column creating standing sound waves . Third resonance occurs when length of water column becomes equal to 5 x λ / 4 . where λ is wave length of sound.
In resonance frequency of air column and tuning fork becomes equal .
Here if L be the length of air column for third resonance
L = 5 x λ / 4
frequency of tuning fork = 512
wavelength of sound produced = velocity of sound / frequency
343 / 512
λ = .6699 m
L = 5 x .6699 / 4
= .8374 m
= 83.74 cm .
water level will be 83.74 cm deep.
