Question

speed is 3×10^8 and frequency is 10000hz calculate wavelength ​

Answer 1

Answer:

As we have

C= lemda × frequency

Or

Lemda = c/ frequency

= 3×10^8 / 10^4

Solving above we get

Wavelength = 3×10^4 meters

Answer 2

Solution :

• speed of wave = 3 × 10⁸ m/s
• frequency = 10000hz
• Wavelength = ???

λ = v/f

where,

• λ = wavelength
• v = speed of wave
• f = frequency

›› λ = 3 × 10⁸/10⁴

›› λ = 3 × 10⁸ - ⁴

›› λ = 3 × 10⁴

›› λ = 30000 m

SI unit's :

• SI unit of frequency is m/s
• SI unit of wavelength is m
• SI unit of frequency is Hertz (Hz)
