They lacked a definitive answer.
A. Move energy from one place to another.
Everything from Ultra Low Frequency Radio Frequencies (under about 1Hz) through High Energy Gamma Rays. Visible light is somewhere in middle.
No. Ecologists study nature and scientists study just about everything.Further answerAn ecologist is a scientist, but not all scientists are ecologists.
nature versus nurture
they are conducting experiments.
the particle nature of electromagnetic radiation.
The energy is called electromagnetic radiation (light energy).
Light is known to be electromagnetic radiation, and as such it is of waveform nature. As a waveform, it has wavelength and its counterpart frequency.
The radiations are electromagnetic waves ,they don't require any medium for their travel.
Yes. Alpha particles are helium nuclei. Beta particles are electrons. Gamma rays consist of high frequency electromagnetic radiation. Modern physics has shown that electromagnetic radiation(EMR), including gamma, do not have a wave nature only, but also a particulate nature. Einstein said that EMR are made of photons.
A. Move energy from one place to another.
The evidence is, among others, in interference experiments, which indicate a wave nature. The only evidence we have is the fact that all electromagnetic radiation exhibits refraction, reflection, diffraction, dispersion, constructive and destructive interference, and that each of these behaviors is accurately predicted and described by the math of wave-motion that matches the frequency of the radiation.
Radiation is the transfer of energy by electromagnetic waves. Considering the dual nature of electromagnetic radiation, you could also consider it to be transferred by photons of the electromagnetic radiation. The rate of transfer of radiation is given by the surface area of the radiation source, the surface area of the object receiving the radiation, a geometric coefficient accounting for how much of the radiation from the source actually hits the receiving object, a physical constant called the Stephan-Boltzman constant, the reflectivity, transparency, and absorbtivity of the receiving object for the wavelengths of the radiated energy, and the difference in the 4th power of the thermodynamic temperatures of the objects.
Any wave has an associated particle, and vice versa. However, at very low energies - such as radio waves - the wave nature stands out more; the particle nature is hard to detect in such a case.
The nature vs nurture debate is a scientific, cultural, and mostly philosophical debate. The debate is about whether human culture, personality, and behavior are caused primarily by nature or by nurture.
It is the interaction between environmental factors and biological inheritance that is important in human development
Light was not invented, but is a naturally occurring phenomenon in nature. Visible light is the result of electromagnetic radiation that has a wavelength in the range of 380 to 740 nanometers. Light is emitted by photons, which have the properties of both waves and particles. In nature, sources of light are most commonly thermal in nature, such as the Sun, which emits black-body radiation.
