Because to avoid destructive interference, the end-points must be fixed. That makes them nodes of the wave and so the length of the space must be an integer multiple of half-wavelengths.
An orange that you eat has molecules and the color orange only has photons of a specific frequency.
Space suits and space food are specially manufactured. They are not available everywhere but only specific areas.

A confined reel is a competition in a feis where you dance your normal reel, however a confined reel can only be danced by those who have not won a 3 adjudicator championship.
In plane forces, all forces are confined to a two-dimensional plane, while in space forces, forces can act in three dimensions. Plane forces involve only forces in the x and y axes, while space forces can include forces in the z axis as well. Space forces require vector analysis in three dimensions, while plane forces use scalar analysis in two dimensions.
Both. But that's still only one relationship, because the wavelength and frequency are tightly related ... if you specify one, you've specified both.
The word to describe the number of times a particular event occurs in a specific time is frequency. For example, "Describe the frequency of these pains over the last day or two." Curiously, we are only able to measure time at all because there are some events which we believe to have a frequency which changes only minimally, and so the frequency of other events can be compared to them.
dc does not have frequency only ac
You need to get out in the company of others; your hurt and disappointment will only intensify if you stay confined here in your room.
A: The antenna is designed to receiver a specific band of frequency but the receiver will discriminate all signals except the one of interest otherwise all channels will fight for dominance
A monochromatic spectrum contains only specific wavelengths of light, typically consisting of a single pure color. This type of spectrum is characterized by a narrow band of wavelengths with little to no variation in frequency or energy.
A fundamental tone has only one frequency. It is the lowest frequency produced by a vibrating object and is also known as the first harmonic.
