Can destructive interference occur in waves of different frequencies?

Yes, because propagation speeds may vary.
Beware the conventional error in considering only 'frequency' which is a metaphysical conception requiring 'time'. Much confusion arises from this error.
The proper 'real' scalar directly producing interference effects is 'WAVELENGTH'.

Destructive interference occur because of what?
a
What is formed when constructive and destructive interference occur at the same time?
Standing wave
What is formed when constructive and destructive interference occur at the same time in a wave?
How? Pick one. Will not have both.
What type of interference occurs when two waves are in phase?
Constructive
Distinguish between constructive interference and destructive interference?
Constructive interferences occur when two waves combine (add up) by the superpostition principle. Destructive interferences occur when the crest of one wave interferes with the trough of another. Amplitudes are subtracted.

Lowest frequency at which destructive interference is observed?
Constructive and destructive interference can occur at any frequency. Superposition of waves is not dependent on a specific frequency.
What is formed when constructive and destructive interference occur at the same time?
Standing wave

How can incandescent light be made coherent?
Theoretically it cannot as destructive interference between incoherant wave trains occur (i.e. photons are released spontaneously)

Why does destructive interference occur when the path lengths from two identical sources differ by half a wavelength?
because the crest and the troughs interfere with each other and cancel
Can A standing wave can only occur at natural frequencies?
A standing wave can occur only at specific frequencies that are called natural frequencies.
What is sound made by the wind called?
What we call sound are in fact just pressurewaves propagating through the air. Our ears and brain detect and convert these pressure waves to electric signals which we interprete as being sound. The frequency of these waves determines the altitude of the tone, while the amplitude defines the volume of the sound.When waves (eg pressure waves) pass through openings that have about the same magnitude (or less) than the wavelength of the incident wave, diffraction will occur. Once passed through the opening, diffraction will "generate" a phase difference between waves starting from the top and bottom of the opening. This phase difference leads to interference. Phenomena like diffraction and interference of waves will alter the caracteristics of the incident wave. For example, some frequencies can be cancelled out while others may become bigger. This is what happens in constructive and destructive interference. Different frequencies lead to different sounds because of the connection between frequency and sound.
