In close pipe resonator high pressure reflects as low pressure
1) True
2) False

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.
