Electromagnetic Spectrum

What happens to the energy of a photon as the frequency of the electromagnetic wave increases?

• The energy of the photon decreases as the frequency increases.

• The energy of the photon remains constant regardless of frequency.

• The energy of the photon increases as the frequency increases.

• The energy of the photon fluctuates randomly with frequency.

How does the energy of a photon relate to its wavelength?

• The energy of a photon is directly proportional to its wavelength; shorter wavelengths correspond to lower energy.

• The energy of a photon is inversely proportional to its wavelength; shorter wavelengths correspond to higher energy.

• The energy of a photon is independent of its wavelength; all photons have the same energy.

• The energy of a photon increases with increasing wavelength; longer wavelengths correspond to higher energy.

What is the effect of increasing frequency on the energy of electromagnetic radiation?

• Increasing frequency results in lower energy of the electromagnetic radiation.

• Increasing frequency results in higher energy of the electromagnetic radiation.

• Increasing frequency has no effect on the energy of electromagnetic radiation.

• Increasing frequency results in the energy becoming constant.

What is the electromagnetic spectrum?

• The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by frequency or wavelength.

• The electromagnetic spectrum is a type of sound wave that travels through air.

• The electromagnetic spectrum refers to the visible light spectrum only.

• The electromagnetic spectrum is a measure of gravitational waves in space.

How does wavelength relate to frequency and energy in electromagnetic waves?

• A wave with a large wavelength has a low frequency and low energy.

• A wave with a large wavelength has a high frequency and high energy.

• A wave with a small wavelength has a low frequency and high energy.

• A wave with a small wavelength has a high frequency and low energy.

What distinguishes electromagnetic waves from mechanical waves?

• Electromagnetic waves can travel through empty space, while mechanical waves require a medium.

• Mechanical waves can travel through empty space, while electromagnetic waves require a medium.

• Both electromagnetic and mechanical waves can travel through empty space.

• Electromagnetic waves are slower than mechanical waves.

What is the role of photons in electromagnetic waves?

• Photons are the quantum particles that carry electromagnetic energy and are associated with electromagnetic waves.

• Photons are responsible for the gravitational force in electromagnetic waves.

• Photons are the particles that create sound waves in electromagnetic waves.

• Photons are the particles that absorb electromagnetic waves.

Define electromagnetic waves.

• Electromagnetic waves are particles that travel through a vacuum at the speed of light.

• Electromagnetic waves are oscillations of electric and magnetic fields that carry energy through space.

• Electromagnetic waves are sound waves that can travel through air and water.

• Electromagnetic waves are static fields that do not carry energy.

How do electromagnetic waves carry energy?

• Through the movement of charged particles in a conductor.

• By the oscillation of electric and magnetic fields.

• Via the transfer of thermal energy from one medium to another.

• Through the compression and rarefaction of air molecules.
