The Sun is said to be extremely noisy, but we can’t hear it since sound doesn’t travel through space. Scientists at the University of Sheffield decided to use vibrations within our star's ...
The discovery of the photoacoustic effect dates back to 1880, when Alexander Graham Bell was experimenting with long-distance sound transmission. Through his invention, called "photophone", he transmitted vocal signals by reflecting sun-light from a moving mirror to a selenium solar cell receiver. [3]
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
When sound is moving through a medium that does not have constant physical properties, it may be refracted (either dispersed or focused). [5] Spherical compression (longitudinal) waves. The mechanical vibrations that can be interpreted as sound can travel through all forms of matter: gases, liquids, solids, and plasmas.
The process of photosynthesis provides the main input of free energy into the biosphere, and is one of four main ways in which radiation is important for plant life. [ 114 ] The radiation climate within plant communities is extremely variable, in both time and space.
Human ears cannot hear them, but other plants or animals might.
We can listen to Jupiter's magnetic field interact with solar wind. We can "hear" the sun, passing comets or even pulsars 1,000 light-years from Earth. How to 'listen' to the eerie sounds of space
This word is taken from two Greek words, photos, which means light, and synthesis, which in chemistry means making a substance by combining simpler substances. So, in the presence of light, synthesis of food is called 'photosynthesis'. Noncyclic photophosphorylation through light-dependent reactions of photosynthesis at the thylakoid membrane.
