Answer:

Explanation:
As we know by the law of diffraction through circular aperture

here we know that
a = diameter of the aperture
= diffraction angle
= wavelength
now we have

Now in order to find the wavelength we know



now we have



The best statement would be number 3. Sound waves move perpendicular to the medium particles.

Explanation:
Resistance opposes current thereby reducing the amount of current that flows through a circuit. In other words, it leads to a loss of electrical energy.
Ideally speaking, a good circuit should have no internal resistance as this would lead to more energy having to be supplied to overcome that resistance. External resistance however, is not a bad thing. For instance, oxygen being removed from lightbulbs.
