A wave has a period of 2 seconds and a wavelength of 4 meters. Calculate its frequency and speed. Note: Recall that the frequency of a wave equals 1/period & the period of a wave equals 1/frequency.

frequency = 0.5 Hz and speed = 2 m/s

Explanation:

Given that,

The period of a wave, T = 2 s

Wavelength,

If f be the frequency. So,

f = 1/T

Speed of a wave is given by :

So, the frequency of the wave is 0.5 Hz and speed is 2 m/s.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
