Question

the wavelength of light having frequency 60mhzis​

Answer 1

Answer:

5 × 10^9 m

Step-by-step explanation:

Wavelength and Frequency (f) are related as

• wavelength = c/f

where c is velocity of light (3 × 10^8 m/s)

Given that frequency is 60 mHz which is equal to 60 × 10^-3 Hz

Wavelength = (3 × 10^8 m/s) / (60 × 10^-3 Hz)

= 5 × 10^9 m

Note: 1 mHz = 10^-3 Hz whereas 1 MHz = 10^6 Hz

Answer 2

Answer:5m

Step-by-step explanation:

We know,

C=lambda × frequency

Or, 3×10^8=(lambda)×60×10^6

Or, (3×10^8)/(60×10^6)=lambda

Or, 300/60=lambda

Or,lambda=5m
