- 2020 May 12, Dr Glyn Morris, “Chwalu'r chwedlau am coronafeirws”, in BBC Cymru Fyw[1]:
- Ond os ofynnwch (sic) i ffisegydd, bydden nhw'n dweud bod tonfedd y lliw coch bob amser yn bresennol, ac felly mae'r datganiad yn wir.
- But if you ask a physicist, they would say that the wavelength of the color red is always present, and so the statement is true.
