Concept explainers
Interpretation:
The momentum of a photon of light having wavelength
Concept introduction:
Momentum is the product of mass and velocity of a moving particle. It is denoted by
The de Broglie equation is related to the particle and wave properties. It is expressed as follows:

- When the Sojourner spacecraft landed on Mars in 1997, the planet was approximately 7.8 107 km from Earth. How long did it take for the television picture signal to reach Earth from Mars?arrow_forwardRadio waves in the AM region have frequencies in the range 530 to 1700 kilocycles per second (530 to 1700 kHz). Calculate the wavelength corresponding to a radio wave of frequency 1.460 106/s (that is, 1460 kHz).arrow_forwardA particular transition of the rubidium atom emits light whose frequency is 3.84 1014 Hz. (Hz is the abbreviation for hertz, which is equivalent to the unit/s, or s1.) Is this light in the visible spectrum? If so, what is the color of the light? (See Figure 7.5.)arrow_forward
- The most prominent line in the spectrum of mercury is at 253.652 nm. Other lines are located at 365.015 nm, 404.656 nm, 435.833 nm, and 101.975 nm. (a) which of these lines represents the most energetic light? (b) what is the frequency of the most prominent line? What is the energy of one photon with this wavelength? (c) Are any of these lines found in the spectrum of mercury shown in figure 6.6? What color or colors are these lines?arrow_forwardConsider the colors of the visible spectrum. (a) Which colors of light involve less energy than green light? (b) Which color of light has photons of greater energy, yellow or blue? (c) Which color of light has the higher frequency, blue or green?arrow_forwardA lightbulb radiates 8.5% of the energy supplied to it as visible light. If the wavelength of the visible light is assumed to be 565 nm, how many photons per second are emitted by a 75-W lightbulb? (1W=1J/s)arrow_forward
- One type of solar radiation in the upper atmosphere has a frequency of 7.898 1014 Hz; another type has a frequency of 1.20 1015 Hz. (a) In what region of the electromagnetic spectrum does this solar radiation occur? (b) Which of the two types of radiation has the shorter wavelength? Explain your answer.arrow_forwardMicrowaves have frequencies in the range 109 to 1012/s (cycles per second), equivalent to between 1 gigahertz and 1 terahertz. What is the wavelength of microwave radiation whose frequency is 1.395 1010/s?arrow_forwardSelenium atoms have a particular transition that emits light of frequency 1.53 1015 Hz. (Hz is the abbreviation for hertz, which is equivalent to the unit/s, or s1.) Is this light in the visible spectrum? If so, what is the color of the light? (See Figure 7.5.)arrow_forward
