A wave is characterized by its frequency, wavelength, amplitude and polarization. The possible frequencies of electromagnetic waves extend from the extremely high frequencies of the gamma rays to the relatively low frequencies of the radio waves. Visible light is...
9) Calculate the wavelength in a vacuum of X-rays of frequency 1.3 × 10^(17)Hz 相关知识点: 试题来源: 解析 2.31 * 10^(-9) 米 根据光速、频率和波长之间的关系公式 c = λ * f,其中 c 为光速,λ 为波长,f 为频率,可得波长 λ = c/f。将已知光速 c = 3.00 * 10^8 m/s 和频率 f...
Answer to: Calculate the wavelength, in nanometers, of x-rays having a frequency of 4.2 x 1016 Hz. By signing up, you'll get thousands of...
The distance between one peak of a wave to the next corresponding peak, or between any two adjacent corresponding points, defined as the speed of a wave divided by its frequency. Idiom: on the same wavelengthInformal In complete accord; in harmony:"a fluid ... production in which author, ...
(a) Find the maximum frequency of the X-rays emitted by an X-ray tube operating at30kV. (b) An X-ray tube operates at20kV. A particular electron loses5%of its kinetic energy to emit an X-ray photon at the first collision. Find the wavelength corresponding to this photon. ...
