He Period refers to the time it takes an individual particle (or coil) to complete one back and forth vibration about its fixed position. Contrast a low period set of continuous vibrations with a high period set of continuous vibrations. Which leads to a higher frequency of vibration of individual particles (i. e., coils)? Which leads to a longer wavelength

The answer are

A low period set of continuous vibrations

A high period gives a higher wavelength

Explanation:

The relationship between period and frequency is given as

T = 1/F

Therefore a higher period gives a lower frequency while a low period gives a higher frequency.

In expressing the velocity of the wave in terms of period and frequency, we have that v = frequency × wavelength

frequency = velocity / wavelength

Giving us that the period is equal to wavelength / velocity,

From the relationship A high period gives a longer wavelength while a short period gives a shorter wavelength.

Thus the question is easily solved from the equations.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
