Concept introduction:
Light is measured by its wavelength (in nanometres) or frequency (in Hertz).
One wavelength equals the distance between two successive wave crests or troughs.
Frequency (Hertz) equals the number of waves that passes a given point per second.
The relation between the
Here,
The frequency of the electromagnetic radiation is used to determine the amount of energy, which is carried by one of its photons.
The energy of the photon is directly proportional to the frequency.
Here,
The relation between a nanometer and a meter is as:
The conversion factor to obtain the units of wavelength in

- 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_forward(a) Which color in the visible spectrum has the highest frequency? Which has the lowest frequency? (b) Is the wavelength of the radiation used in a microwave oven (2.45 GHz) longer or shorter than that from your favorite FM radio station (for example, 91.7 MHz)? (c) Are the wavelengths of x-rays longer or shorter than those of ultraviolet light?

- Suppose hydrogen atoms absorb energy so that electrons are excited to the n = 7 energy level. Electrons then undergo these transitions, among others: (a) n = 7 n = 1; (b) n = 7 n = 6; and (c) n = 2 n = 1. Which of these transitions produces a photon with (i) the smallest energy, (ii) the highest frequency, and (iii) the shortest wavelength?arrow_forwardFour types of electromagnetic radiation (EMR) are ultraviolet, microwaves, gamma rays, and visible. All of these types of EMR can be characterized by wavelength, frequency, photon energy, and speed of travel. Define these terms and rank the four types of electromagnetic radiation in order of increasing wavelength, frequency, photon energy, and speed.arrow_forwardConsider only transitions involving the n = 1 through n = 5 energy levels for the H atom (see Figures 6.7 and 6.10). (a) How many emission lines are possible, considering only the five quantum levels? (b) Photons of the highest frequency are emitted in a transition from the level with n = ______ to a level with n = ______. (c) The emission line having the longest wavelength corresponds to a transition from the level with n = ______ to the level with n = _________.arrow_forward
- One type of electromagnetic radiation has a frequency of 107.1 MHz, another type has a wavelength of 2.12 1010 m, and another type of electromagnetic radiation has photons with energy equal to 3.97 1019 J/pboton. Identify each type of electromagnetic radiation and place them in order of increasing photon energy and increasing frequency.arrow_forwardA cell phone sends signals at about 850 MHz (where 1 MHz = 1 106 Hz or cycles per second).

These three different types of cones interact with photons of different frequency light, as indicated in the following chart: Cone Type Range of Light Frequency Detected S 6.00-7.49 1014s1 M 4.76-6.62 1014s1 L 4.28-6.00 1014s1 What wavelength ranges (and corresponding colors) do the three types of cones detect?arrow_forward
- RGB color television and computer displays use cathode ray tubes that produce colors by mixing red, green, and blue light. If we look at the screen with a magnifying glass, we can see individual dots turn on and off as the colors change. Using a spectrum of visible light, determine the approximate wavelength of each of these colors. What is the frequency and energy of a photon of each of these colors?arrow_forwardA photon with a wavelength of 93.8 nm strikes a hydrogen atom, and light is emitted by the atom. How many emission lines would be observed? At what wavelengths? Explain briefly (see Figure 6.10).arrow_forward
