What light does as it passes from one medium to another?
Light changes speed and direction as it passes from one medium to another due to the change in density between the two media. This change in speed and direction is known as refraction.
Explain how a beam of light passing through a diffuse cloud may give rise to both absorption and emission spectra?
When a light passes through a diffuse cloud, part of the light will be reflected, part will be absorbed, and the rest will pass through depending on the density of the cloud and the energy of the light.The light's energy can be expressed by: E = h(Planck's constant)*nu(frequency)
What colors of light passes most easily through interstellar clouds?
Red light passes most easily through interstellar clouds because it has the longest wavelength and lower energy, making it less likely to be absorbed or scattered by dust particles within the cloud. Blue and violet light, with shorter wavelengths and higher energy, are more likely to be scattered or absorbed.
What happens to th radiation as it passes through earth atmosphere?
As radiation passes through Earth's atmosphere, some of it is absorbed and scattered by gases and particles. This can result in attenuation of the radiation, meaning that its intensity decreases. Different types of radiation are affected in various ways based on their energy and wavelength.
Material through which a wave transfers energy?
The material through which a wave transfers energy is called a medium. In a medium, such as air, water, or solids, particles vibrate or move as the wave passes through, transferring energy from one point to another. Waves can also propagate through vacuum, as seen in the case of electromagnetic waves.
Why is there a change in rate of energy exchange as time passes?
The change in the rate of energy exchange over time can be influenced by various factors such as changes in temperature, system boundaries, and the dynamics of the system itself. As the system evolves, its internal energy distribution and external conditions may also change, leading to fluctuations in the rate of energy exchange.
Does energy change when it passes through a light bulb filament?
The energy won't change
How does energy change when it passes through a light bulb filament?
When energy passes through a light bulb filament, it is converted primarily into heat and light. The filament's resistance causes the electrical energy to be transformed into thermal energy, which then emits light due to incandescence. Some energy may also be lost as infrared radiation.
In gas exchange what passes from the blood to the alveoli?
Oxygen
What happens as blood passes each cell?
Gas exchange.
What is the energy change in a buzzer?
The energy change in a buzzer typically involves electrical energy being converted to sound energy. When an electric current passes through the buzzer, it causes a magnetic coil to move back and forth rapidly, creating vibrations that produce sound energy in the form of a buzzing sound.
What is the potential energy change to when the flood gates of a dam open?
When the flood gates of a dam open, the potential energy of the water stored behind the dam is converted into kinetic energy as the water flows downstream. This change in potential energy to kinetic energy allows the water to generate electricity as it passes through turbines in the dam.
Does light's Energy Decreases as it travels from air into water?
No the Energy of the light doesn't change when it passes through rarer to denser medium. Only Wavelength changes which cause change in its direction. Since Frequency is directly proportional to the Energy and frequency is constant during refraction therefore the energy also remain constant.
What energy change takes place in a electric fire?
In an electric fire, electrical energy is converted into heat energy. The electricity passes through a resistor which generates heat through resistance, thus producing warmth and light in the process.
What happens to its potential energy as it passes to the lowest point?
potential energy changes to kinetic energy
Why does pressure not change when viscous fluid passes through varying cross sectional area?
I am satisfide that the pressure should be changed according to Energy Ballance equation
What is the job of the respritory system?
the respiratory system passes the air you breathe into the lungs for gas exchange .
