Which of the following applications relies on the use of photons?
Explanation: The correct answer is D) All of the above. Photons play a crucial role in various applications. Solar panels convert photons from sunlight into electrical energy, MRI uses photons to generate images of the body's internal structures, and optical fiber communication relies on transmitting information through photons in optical fibers.
Which of the following applications utilizes the wave-like nature of light?
Explanation: The correct answer is C) Holography. Holography is an application that utilizes the wave-like nature of light. Holograms are created by recording and reconstructing the interference patterns of light waves, capturing the phase information and enabling the creation of three-dimensional images.
Which application uses the phenomenon of fluorescence?
Explanation: The correct answer is B) Fluorescent lighting. Fluorescent lighting relies on the phenomenon of fluorescence, where certain materials emit light of a different color (lower energy) after absorbing photons of higher energy. This process helps produce visible light efficiently in fluorescent lamps.
Which of the following applications uses the amplification of light through stimulated emission?
Explanation: The correct answer is C) Laser therapy. Laser therapy utilizes the amplification of light through stimulated emission. In lasers, the process of stimulated emission produces a coherent beam of light with specific properties, allowing it to be focused and directed for various medical treatments.
Which application uses the interaction of photons with electrons to create digital images?
Explanation: The correct answer is A) Digital photography. Digital photography uses the interaction of photons with electrons in image sensors to capture and convert light into digital images. Photons are detected by the image sensor, and the resulting electrical signals are processed to create digital photographs.
