Ann. II. 113 As a rule a much greater photo-electric effect is produced by the more refrangible rays than by the less refrangible. 1903 Philos. Trans. (Royal Soc.) A. 201 535 This was ultimately found to be due to the photoelectric effect produced by the light present in the room. 1935 C. J. Smith Intermediate Physics (ed. 2) v. li. 881–2 For sodium there is no photoelectric effect unless the incident light has a frequency greater than about 5 × 1014 (green light). 1973 J. Yarwood Electr. & Magn. xv. 594 There are three main photoelectric effects. 1993 S. W. Hawking Black Holes & Baby Universes (BNC) 77 The full implications of the photoelectric effect were not realized until 1925, when Werner Heisenberg pointed out that it made it impossible to measure the position of a particle exactly. < as lemmas |
