Electron transitions from higher to lower energy levels cause emission of energy in the form of electromagnetic waves, each with their own specific wavelength. Because the energy levels of elements are quantized, each transition has a specific energy difference. The collection of these transitions makes up the emission spectrum and each spectrum is unique to a specific element, allowing identification.
Answer:
Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body's tissues. ... Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you've been drinking alcohol.Oxygen becomes rapidly toxic at depth – prolonged exposure to pure oxygen below a few metres can kill you. It is not an appropriate scuba tank gas mixture. ... Oxygen is also highly reactive and can make other substances flammable. Safety training is necessary to work with pure oxygen.

From the relationship between wavelength and frequency, the frequency of the wave is reduced by half to 60 Hz as the wavelength is increased twice to 10 m at constant speed.
<h3>What is the relationship between wavelength, velocity and frequency of a wave?</h3>
The velocity, frequency and wavelength of a wave are related by the formula given below:
where
- v is velocity
- f is frequency
- λ is wavelength of the wave
From the above relationship:
If the wavelength of a wave is increased to 10m but the speed stays the same at 600 m/s, the frequency can be calculated as follows:
f = v/λ
f = 600/10
f = 60 Hz
Therefore, the frequency of the wave is reduced by half as the wavelength is increased twice at constant speed.

Answer:
cobalt (Co) is the correct answer.
Explanation:
The is most likely to bend without breaking element is cobalt because of the following properties.
- Cobalt is a ferromagnetic metal.
- Cobalt is a brittle and hard element.
- cobalt is not a nonmetal, it is a metal and metals are malleable and ductile means they can bend without breaking.
Hence Cobalt in their solid form they can be easily bent and changed into thin films without breaking
