Answer: The correct answer is a.

Explanation:

Electromagnetic wave is a wave in which the magnetic field and the electric field are perpendicular to each other.

Both fields are directed in the direction of the propagation of the electromagnetic wave. It travels with the speed of the light.

The motion of the electric field produces both electric field and the magnetic field.

The electromagnetic waves are produced when an electric charge vibrates or accelerates.

Therefore, the correct option is (a).

Answer:

330.24 Hz

Explanation:

Given:

Frequency, f = 320 Hz

L1 = 25.8 cm

L2 = 78.4 cm

L3 = 131.1 cm

Let the wavelength be λ

Then, L1 which is the length of the column of air is  λ/4.

λ/4 = 25.8 cm

λ = 25.8 × 4 = 103.2 cm = 1.032 m

Then, speed of sound in air is:

v = λ f

⇒ v = 1.032 × 320 Hz

⇒ v = 330.24 m/s
