The parabolic reflector transforms an incoming plane wave traveling along the axis into a spherical wave converging toward the focus.

At the critical Mach number, local airflow in some areas near the airframe reaches the speed of sound, even though the aircraft itself has an airspeed lower than Mach 1.0.

What kind of wave?

Great wave ? Yeah.

The hijackers moved to the rear of the plane.

Over longer distances, a shock wave can change from a nonlinear wave into a linear wave, degenerating into a conventional sound wave as it heats the air and loses energy.

Airplane!

This is a pulse wave because we only have, essentially, one perturbation of the string.

The plane crashed.

The hummingbird?

On the plane.

The wreck of the plane.

Where's an airplane?

(Applause.) As the tide of war recedes, a wave of change has washed across the Middle East and North Africa, from Tunis to Cairo from Sana'a to Tripoli.

Shall we create a Wave of Bliss?

There was a wave all right.

let's focus on a jet plane. A jet plane has to travel through the air

On my way here on the airplane, I was walking up and down the aisle of the plane.

The airplane made a safe landing.

Let's play volleyball.

I got on an airplane.

Until the jet limit

The product was that airplane.

I conceived the kind of airplane.

I didn't check the airplane.

The plane to Lisbon.

Didn't it go?

In a plane?

Get the next plane.

Oh, the wreck of the plane.

About the plane, you mean?

I said, Get yourself on the plane.
