A transverse wave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.
A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling. Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.
Similarities
- Both transverse and longitudinal waves carry energy.
- Both transverse and longitudinal waves obey the wave equation.
- Both transverse and longitudinal waves show behavior such as refraction, reflection, absorption, diffraction, etc.
Differences
The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.
Answer: Order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Explanation: Reactivity of the elements is the tendency of the elements to loose or gain electrons with ease.
As, all the given elements are metals, so the metals which will loose electrons easily will be more reactive. To study the reactivity of metals, we use reactivity series.
The metals which are more reactive are placed on the top of the reactivity series and which are less reactive are placed at the bottom.
Hence, the order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Reactivity series is attached below.
nabr + cacl2 are the products

The branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Answer:
there are some materials listed so next to it it shows that which material is pure substance and which material is mixture
and then the next shows which is a homologous and homogeneous compound or element
