Test tube
In a tube closed at one end, only odd harmonics are produced. This is because the closed end acts as a node for the pressure wave, leading to a fundamental frequency and odd harmonics of that frequency.
To produce a standing wave in a tube that is open at one end and closed at the other end, the length of the tube must be an integer multiple of one-fourth of the wavelength of the wave. This condition allows for constructive interference at the closed end and destructive interference at the open end, resulting in a standing wave pattern. Additionally, the frequency of the wave must be such that the boundary conditions of the tube are satisfied.
The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.
The velocity of sound in air can be calculated using the formula v = f * λ, where v is the velocity of sound, f is the frequency of the sound wave, and λ is the wavelength. In a resonance tube closed at one end, the first resonance occurs when the length of the tube is one-fourth of the wavelength of the sound wave produced. This information can be used to calculate the velocity of sound in air.
It is a thermometer, and is used to show the temperature.
The head end of a tube can be the closed end. This depends on what the tube's purpose in the car is.
In a tube closed at one end, only odd harmonics are produced. This is because the closed end acts as a node for the pressure wave, leading to a fundamental frequency and odd harmonics of that frequency.
Construction of a kaleidoscope:Three rectangular mirror strips of dimensions 15cm × 4cm (l × b) are joined together to form a prism (fig a). This prism is fixed into a circular cardboard tube. The circular cardboard tube should be slightly longer that the prism (fig b). This circular tube is now closed at one end with a cardboard disc. This disc has a hole in it through which we can see (fig c) .At the other end of the circular tube, a plane glass plate is fixed. It is important that this glass plate touches the prism mirrors. On this glass plate, several small and broken pieces of coloured glass are placed. This end is now closed by a round glass plate allowing enough space for the coloured glass pieces to move (fig d).
A test tube is a cylindrical, transparent glass tube with a rounded bottom and open top. It is used for holding and mixing liquids in scientific experiments. Test tubes can vary in size and may have markings or graduations on the side for measuring liquid volumes.

A manometer. Used to measure pressure.
Well, Basically, its a tube with a scope, but with the rocket loaded inside of it, it looks like a tube with glass Coke bottle on the end.
Thermometer
The length of the tube and the wavelength of the given wave must match up accordingly so that there is an anti-node at the open end and a node at the closed end.
