Answer
given,
at time t = 10 s moving from left to right speed of particle = 5 m/s
at t = 20 s moving from right to left speed of particle is = 8 m/s
a) acceleration
a = -1.3 m/s²
b) using equation of motion
v = u + at
5 = u - 1.3 × 10
u = 5 + 13
u = 18 m/s
c) v = u + at
0 = 18 - 1.3t
t = 13.85 s
This should be using the wavelength-frequency formula: c=fλ
λ (Lambda) = Wavelength in meters
c = Speed of Light ( m/s)
f = Frequency (Hz)
So 3e8/1 = 3e8 Hz
