What is psychophysical theory? Psychophysics has been described as “the scientific study of the relation between stimulus and sensation” or, more completely, as “the analysis of perceptual processes by studying the effect on a subject’s experience or behaviour of systematically varying the properties of a stimulus along one or more physical … Why is psychophysics […]
Does reflected light lose energy?
Does reflected light lose energy? Often it does not lose much energy on being reflected. It loses energy on being absorbed. Each reflected photon has the same energy as before. Light may lose or gain energy on being reflected from a moving mirror because of the Doppler shift. What happen when light is reflected refracted […]
Is oxitec funded by Bill Gates?
Is oxitec funded by Bill Gates? As reported by Axios , the company, which is funded by the Bill and Melinda Gates Foundation , released the mosquitoes a week ago from the Florida Keys. Oxitec noted that this species only represents 4% of the mosquito population in Florida, but it is the most disease-transmitting species. […]
What are signs of food spoilage?
What are signs of food spoilage? Signs of food spoilage may include an appearance different from the food in its fresh form, such as a change in color, a change in texture, an unpleasant odour, or an undesirable taste. The item may become softer than normal. If mold occurs, it is often visible externally on […]
What is the important of scientific method?
What is the important of scientific method? The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can’t escape bias. That’s the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. What is scientific […]
Why is a reflecting telescope better than a refracting?
Why is a reflecting telescope better than a refracting? Reflecting telescopes have a number of other advantages over refractors. They are not subject to chromatic aberration because reflected light does not disperse according to wavelength. Also, the telescope tube of a reflector is shorter than that of a refractor of the same diameter, which reduces […]
What are examples of mixed waste?
What are examples of mixed waste? Mixed hazardous waste is waste which falls into two or more different categories of hazardous materials. Examples include radioactive contaminated phenol/chloroform, or blood labeled with a radionuclide. How long does low-level waste need to be stored? Disposal of low-level waste is straightforward and can be undertaken safely almost anywhere. […]
Which condition causes changes in air pressure in the atmosphere?
Which condition causes changes in air pressure in the atmosphere? This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air. […]
What is viscosity and its type?
What is viscosity and its type? Viscosity is defined as the measure of the resistance of a fluid to gradual deformation by shear or tensile stress. In other words, viscosity describes a fluid’s resistance to flow. Simply put, we can say that honey is thicker than water; in turn, honey is more viscous than water. […]
What are the similarities and differences between a convergent and a divergent zone?
What are the similarities and differences between a convergent and a divergent zone? In summary the Divergent and Convergent plate margins have similar and different topographical features that would have been formed or is still forming as a result of tectonic plate movement. The similarities are volcanoes and mountain ranges while the differences are rift […]
