Question

Speed of a sound in air is 300 metre per second distance between two successive nodes of a stationary wave of frequency 100 Hertz

Answer 1

Answer:

The distance between and two successive troughs or crusts in a wave is known as Wavelength denoted by the Greek letter Lambda (λ).

We know that,

Wavelength (λ) = Speed ÷ Frequency (υ)

According to the question,

• Wavelength = ?
• Speed of Sound = 300 m/s
• Frequency = 100 Hz

Substituting in the above formula we get,

→ Wavelength = 300 m/s ÷ 100 Hz

→ Wavelength = 3 m

Therefore the distance between 2 successive nodes of a stationary wave is 3 m.

Answer 2

Answer:

3 m

Explanation:

Given :

Speed of sound = 300 m / sec

Frequency = 100 Hz

We have to find wave length

We know :

λ = v / ν

λ = 300 / 100 m

λ = 3 m .

Hence distance between two successive nodes is 3 m.
