Solution:

frequency = 50/25 = 2Hz

wavelength = speed of light $\xf7$ freqency

$=3\times {10}^{7}\xf72$

Now, $=1.5\times {10}^{7}m$

speed = 2m $\xf7$ 4s

Answer: = 0.5 m/s

frequency = 50/25 = 2Hz

wavelength = speed of light $\xf7$ freqency

$=3\times {10}^{7}\xf72$

Now, $=1.5\times {10}^{7}m$

speed = 2m $\xf7$ 4s

Answer: = 0.5 m/s
