(b) A light wave from a laser has a wavelength of 460nm in a vacuum. Calculate the period of the wave.相关知识点: 试题来源: 解析 光波的周期约为1.54×10^-15秒。 光波的周期等于波长除以光速,即T = λ/c。已知波长λ = 460nm = 4.6 × 10⁻⁷ m,光速c = 3.00 × 10⁸ m/s,...
Calculate the wavelength of a sound wave having a frequency300Hzand speed330m/s. View Solution Find the time period of the source of a sound wave whose frequency is 400 Hz. View Solution Velocity of sound is given by the expression,v=f×λ ...
The frequency of a wave transmission is the inverse of the period, which is the time taken for a single cycle. In the case of water waves, a cycle is the time it takes for one complete wave to pass a given point. The period of water waves with a frequency of 0.33 Hz is 1/0.33 ...
To calculate the frequency of a particle wave when the kinetic energy of a sub-atomic particle is given as 3.79×10−27J, we can follow these steps: Step 1: Use the kinetic energy formulaThe kinetic energy (KE) of a particle is given by the formula:KE=12mv2where m is the mass of...
Chen and Haus' theory was used to analyze surface acoustic waves in shorten gratings with single finger every period and a reflection coefficient expression of one strip was presented. Parameters of aluminum on X-112掳Y LiTaO3 and gold on ST-quartz were calculated. The results agreed well with...
