Answer 1

Part-A)

Since wavelength of electromagnetic waves is given by,

= c/f

here, c = 3*10^8 m/s

f = frequency = 7*10^21 Hz

So, 1 = (3*10^8)/(7*10^21)

1 = 4.29*10^-14 m

Part-C)

Since wavelength of electromagnetic waves is given by,

= c/f

here, c = 3*10^8 m/s

f = frequency = 6.5*10^14 Hz

So, 2 = (3*10^8)/(6.5*10^14)

2 = 4.61*10^-7 m
