Light acting as 'packets' of exact amounts of energy (a particle-like quality) called quanta led to the development of quantum mechanics. Light also has wave qualities (wavelength, frequency, amplitude) which is referred to as particle-wave duality.
Answer:
They are emitted from heated objects
Explanation:
When objects are heated, they emit light at all wavelengths thereby forming a continuous spectrum. Electromagnetic radiation of all wavelengths and colours are usually represented in such spectrum. A thermal spectrum is quite a simple spectrum since it depends on temperature.
Alcohol is completely soluble in water in any amounts. That is because every alcohol contains carbon chain and OH group which are non-polar and polar. Any substances or solutes that will be mixed with the alcohol you will just get a simple solution.
