Answer:

f = 0.5 Hz

v = 8 m/s

Explanation:

f = 1/T

f = 1/(2) = 0.5 Hz

v = λf

v = (2)(4) = 8 m/s

3 0

F=l/t
f=4/2
f=2m/s

Hope this helps

Answer:

A. Known variables include

Wavelength = 600nm

Theta= 65°

m= 2

d= m x wavelength / sin theta

= 2 * 600*10^-9 /sin 65°

= 1.3*10^-6m

N = 1/d

So N = 1/1.3*10^-6m

=76.9 lines per micro meter
