    Infrared radiation is sometimes called?   - ProProfs

    Infrared radiation is sometimes called?  

    • Infrared light

    • Electromagnetic field

    • Illumination

    • None of the above

    Correct Answer
    A. Infrared light
    Explanation
    Infrared radiation is sometimes called "Infrared light" because it is a type of electromagnetic radiation with longer wavelengths than visible light. It is not referred to as "Electromagnetic field" or "Illumination" as these terms are not specific to infrared radiation.

    It extends from the nominal red edge of the visible spectrum at?   - ProProfs

    It extends from the nominal red edge of the visible spectrum at?  

    • 650 nanometers

    • 700 nanometers

    • 859 nanometers

    • 600 nanometers

    Correct Answer
    A. 700 nanometers
    Explanation
    The correct answer is 700 nanometers. The red edge of the visible spectrum is the longest wavelength of light that can be perceived by the human eye as red. This wavelength is typically around 650-700 nanometers. Therefore, 700 nanometers is the most reasonable choice as it falls within this range.

    Infrared was discovered in 1800 by astronomer Sir?   - ProProfs

    Infrared was discovered in 1800 by astronomer Sir?  

    • George Moore

    • George Washington

    • Allan Sugar

    • William Herschel

    Correct Answer
    A. William Herschel
    Explanation
    William Herschel, an astronomer, discovered infrared radiation in 1800. He was conducting experiments on the temperature of different colors of light by passing sunlight through a prism and measuring the temperature of each color. Herschel noticed that the temperature increased as he moved the thermometer beyond the red end of the visible spectrum, where no light was visible. This led him to conclude that there must be an invisible form of radiation beyond the red light, which he named "infrared".

    Slightly more than half of the total energy from the Sun was eventually found to arrive on Earth in the form of?   - ProProfs

    Slightly more than half of the total energy from the Sun was eventually found to arrive on Earth in the form of?  

    • Ultra ray

    • Ultra violet

    • Radiation

    • Infrared

    Correct Answer
    A. Infrared
    Explanation
    The correct answer is Infrared. Slightly more than half of the total energy from the Sun arrives on Earth in the form of infrared radiation. Infrared radiation is a type of electromagnetic radiation with longer wavelengths than visible light. It is not visible to the human eye but can be felt as heat. Infrared radiation plays a crucial role in Earth's climate system, as it is absorbed by greenhouse gases in the atmosphere, helping to warm the planet.

    The balance between absorbed and emitted infrared radiation has a critical effect on Earth’s?   - ProProfs

    The balance between absorbed and emitted infrared radiation has a critical effect on Earth’s?  

    • Movement

    • Weather

    • Climate

    • None of the above

    Correct Answer
    A. Climate
    Explanation
    The balance between absorbed and emitted infrared radiation has a critical effect on Earth's climate. Infrared radiation is a form of heat energy that is absorbed and emitted by the Earth and its atmosphere. When there is an imbalance between the amount of infrared radiation absorbed and emitted, it can lead to changes in temperature and weather patterns, which ultimately affect the long-term climate of the planet. Therefore, maintaining a balance between absorbed and emitted infrared radiation is crucial for understanding and predicting climate changes.

    Like EMR, infrared radiation carried radiant energy and behaves like a?   - ProProfs

    Like EMR, infrared radiation carried radiant energy and behaves like a?  

    • Wave

    • Quantum

    • Photon

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Infrared radiation, like EMR, carries radiant energy and behaves like a wave, a quantum, and a photon. Infrared radiation exhibits wave-like properties, such as wavelength and frequency, and can be described as a stream of particles called photons, which have discrete energy levels called quanta. Therefore, all of the above options are correct explanations for the behavior of infrared radiation.

    Infrared radiation is emitted or absorbed by?   - ProProfs

    Infrared radiation is emitted or absorbed by?  

    • Atom

    • Photon

    • Oxygen

    • Molecule

    Correct Answer
    A. Molecule
    Explanation
    Infrared radiation is emitted or absorbed by molecules. This is because infrared radiation corresponds to the energy levels associated with the vibrations and rotations of molecules. When a molecule absorbs infrared radiation, it gains energy and its vibrational or rotational modes are excited. Similarly, when a molecule emits infrared radiation, it releases energy from its vibrational or rotational modes. Atoms, photons, and oxygen do not possess the necessary vibrational or rotational modes to emit or absorb infrared radiation.

    The astronomer discovered a type of invisible radiation in the spectrum lower in?   - ProProfs

    The astronomer discovered a type of invisible radiation in the spectrum lower in?  

    • Rays

    • Energy

    • Light

    • None of the above

    Correct Answer
    A. Energy
    Explanation
    The correct answer is "Energy." The question is asking about a type of invisible radiation that the astronomer discovered in the lower spectrum. Rays and light are both forms of visible radiation, so they cannot be the correct answer. "Energy" is the most suitable answer because radiation is a form of energy that can exist in different parts of the spectrum, including the lower spectrum.

    Infrared radiation excites vibrational modes in a molecule through a change in the?   - ProProfs

    Infrared radiation excites vibrational modes in a molecule through a change in the?  

    • Dipole moment

    • Infrared

    • Atom

    • Sodium

    Correct Answer
    A. Dipole moment
    Explanation
    Infrared radiation excites vibrational modes in a molecule through a change in the dipole moment. This is because infrared radiation interacts with the polar bonds in a molecule, causing the atoms to vibrate. The dipole moment is a measure of the separation of positive and negative charges in a molecule, and a change in this separation leads to the excitation of vibrational modes.
