Concept explainers
The explanation of Planck’s hypothesis that agrees with the classical explanation that objects emit light through the accelerated motion of electrically charged particles.
Answer to Problem 1RQ
Solution:
An accelerated charged particle emits
Explanation of Solution
Introduction:
Planck’s hypothesis stated that an accelerated charged particle can radiate an electromagnetic wave. They radiate energy only in a discrete portion called the quanta.
Explanation:
According to Planck, accelerated charged particles are responsible for electromagnetic radiation. However, they could radiate energy only in a discrete portion called the quanta. Each quantum of emitted energy was equal to the multiple of some fundamental portion of energy. According to Planck, instead of frequency quantization (classical concept), it is the energy of the oscillator that was quantized. Mathematically:
Here,
Conclusion:
Planck’s hypothesis suggested that the energy of the electromagnetic radiation of the oscillator is quantized, rather than the frequency.

- Integrated Concepts A neighboring galaxy rotates on its axis so that stars on one side move toward us as fast as 200 km/s, while those on the other side move away as fast as 200 km/s. This causes the EM radiation we receive to be Doppler shifted by velocities over the entire range of 200 km/s. What range of wavelengths will we observe for the 656.0-nm line in the Balmer series of hydrogen emitted by stars in this galaxy. (This is called line broadening.)arrow_forwardLaser vision correction often uses an excimer laser that produces 193-nm electromagnetic radiation. This wavelength is extremer strongly absorbed by the cornea and athletes it in a manner that reshapes the cornea to correct vision detects. Explain how the strong absorption helps concentrate the energy in a thin layer and thus give greater accuracy in shaping the cornea. Also explain how this strong absorption limits damage to the lens and retina of the eye.arrow_forwardIntegrated Concepts (a) Calculate the velocity of electrons that form the same pattern as 450-nm light when passed through a double slit. (b) Calculate the kinetic energy of each and compare them. (c) Would either be easier to generate than the other? Explain.arrow_forward
- Integrated Concepts Sunlight above the Earth's atmosphere has an intensity of 1.30kW/m2. If this is reflected straight back from a mirror that has only a small recoil, the light's momentum is exactly reversed, giving the mirror twice the incident momentum. (a) Calculate the force per square meter of mirror. (b) Very low mass mirrors can be constructed in the near weightlessness of space, and attached to a spaceship to sail it. Once done, the average mass per square meter of the spaceship is 0.100 kg. Find the acceleration of the spaceship if all other forces are balanced. (c) How fast is it moving 24 hours later?arrow_forwardModels are particularly useful in relativity and quantum mechanics, where conditions are outside those normally encountered by humans. What is a model?arrow_forwardIs the photoelectric effect a direct consequence of the wave character of EM radiation or of the particle character of EM radiation? Explain briefly.arrow_forward
- A light source recedes from an observer with a speed s that is small compared with c. (a) Show that the fractional shift in the measured wavelength is given by the approximate expression =vSc This phenomenon is known as the redshift because the visible light is shifted toward the red. (b) Spectroscopic measurements of light at = 397 nm coming from a galaxy in Ursa Major reveal a redshift of 20.0 nm. What is the recessional speed of the galaxy?arrow_forwardConstruct Your Own Problem Consider the Doppler-shifted hydrogen spectrum received from a rapidly receding galaxy. Construct a problem in which you calculate the energies of selected spectral lines in the Balmer series and examine whether they can be described with a formula like that in the equation 1=R(1nf21ni2), but with a different constant R.arrow_forwardIntegrated Concepts The momentum of light is exactly reversed when reflected straight back from a mirror, assuming negligible recoil of the mirror. Thus the change in momentum is twice the photon momentum. Suppose light of intensity 1.00 kW/m2 reflects from a mirror of area 2.00m2. (a) Calculate the energy reflected in 1.00 s. (b) What is the momentum imparted to the mirror? (c) Using the most general form of Newton's second law, what is the force on the mirror? (d) Does the assumption of no mirror recoil seem reasonable?arrow_forward
