Question 1:

Which of the following statements about photons is correct?

A) Photons are particles of matter
B) Photons are waves of light
C) Photons have both particle and wave properties
D) Photons have neither particle nor wave properties

Show Answer

Explanation: The correct answer is C) Photons have both particle and wave properties. Photons exhibit characteristics of both particles and waves. They are considered as particles of light, but their behavior can be described using wave-like phenomena such as interference and diffraction.

Question 2:

Which of the following statements about the energy of photons is true?

A) The energy of photons depends on their wavelength
B) The energy of photons depends on their frequency
C) The energy of photons depends on their speed
D) The energy of photons is constant

Show Answer

Explanation: The correct answer is B) The energy of photons depends on their frequency. According to the equation E = hf, where E represents the energy of a photon, h is Planck's constant, and f is the frequency of the photon, the energy is directly proportional to the frequency. Higher-frequency photons have higher energy.

Question 3:

Which of the following colors of light has the highest energy per photon?

A) Red
B) Green
C) Blue
D) Yellow

Show Answer

Explanation: The correct answer is C) Blue. The energy per photon is directly proportional to the frequency of the light. Blue light has a higher frequency compared to red, green, or yellow light, and therefore, it has the highest energy per photon among the given options.

Question 4:

Which of the following statements about the electromagnetic spectrum is correct?

A) The electromagnetic spectrum includes only visible light
B) The electromagnetic spectrum includes only radio waves and microwaves
C) The electromagnetic spectrum includes all forms of electromagnetic radiation
D) The electromagnetic spectrum includes only X-rays and gamma rays

Show Answer

Explanation: The correct answer is C) The electromagnetic spectrum includes all forms of electromagnetic radiation. The electromagnetic spectrum encompasses a wide range of electromagnetic waves, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of electromagnetic radiation has a different wavelength and frequency.

Question 5:

Which type of electromagnetic radiation has the shortest wavelength?

A) Radio waves
B) Visible light
C) X-rays
D) Gamma rays

Show Answer

Explanation: The correct answer is D) Gamma rays. Gamma rays have the shortest wavelength among the given options. They are highly energetic electromagnetic waves and are commonly emitted during radioactive decay or nuclear reactions.
