Answer: 1) Wave 1 has larger frequency.
2) 2 complete wavelengths are there from 0- 25 on the x axis
Explanation:
1) Frequency is defined as number of times waves produced with in a particular period of a time. One cycle corresponds to a pair of crest and trough.
In the first diagram ,there are 4 complete cycles and 1 half cycle in the interval of 30 units on the x-axis.
In the second diagram, there 2 complete cycles and 1 one-forth cycle in the interval of 30 on the x-axis.
Wave one has larger frequency than wave 2.
2) 2 Complete wavelengths are there from 0- 25 on the x axis
Wavelength of a wave is defined as distance from one crest to another or distance from one trough to anther trough. In the second diagram there are 2 complete wavelengths from 0 to 25 on axis.
