Answer:
Part a)
Part b)
Explanation:
Part a) What is the period of these waves?
we know that
Since wave frequency (f) is the number of waves per second, and the period (T) is essentially the number of seconds per wave, the relationship between frequency and period is
we have
Remember that
1 Hz is one cycle (or one wave) per second
so
Part b) What is the wave velocity?
we know that
The speed of a wave (v) is equal to the frequency multiplied by the wavelength
we have
so

The correct answer is option A. 1/4 times
This is because distance and force are inversely proportional

Answer:
Wavelength = the distance between two adjacent peaks of the wave.
Explanation:
The wavelength of a wave is defined as the distance between two adjacent peaks of the wave or it is defined as the distance between two consecutive crests and troughs. It is denoted by . Its SI unit is meters.
The relation between the frequency and the wavelength is given by :
Where
v is the speed
So, the correct option is (a). " the distance between two adjacent peaks of the wave".
Answer:
Infrared
Explanation:
The wavelength band that we see is infrared light, this happens because the dust that seems to be dark in the visible light photo becomes visible in infrared light.
