谱线波长 meaning in English
line wavelength
Examples
- For example , if we find that the spectral line of the radiation from a galaxy is of wavelength 515nm , the same spectral line measured on earth has wavelength 500nm , then the redshift z 0 . 03
例如某星系的某一谱线波长为515纳米，但在地球上，同一谱线的波长却为500纳米，那么波长的变化为15纳米，原本波长为500纳米，所以红移量z等于0 . 03 。
