Cel­e­brat­ing the won­ders of light

The Queensland Times - - OPINION -

IN RE­SPONSE to G. Brougham in “It’s all just a re­ac­tion” (QT 14/01), what I found amaz­ing was “light waves emit­ted from the sources are of the same fre­quency (and wave­length) and all are in phase” (Storen and Mar­tine, Physics for Se­nior Stu­dents, Thomas Nel­son, South Mel­bourne, 1987).

This is amaz­ing be­cause of re­cent ap­pli­ca­tions of laser light. One year after my last cataract surgery, I had suc­cess­ful laser treat­ment on that eye.

I thank God I have rea­son­ably good sight be­cause of the won­ders of his uni­verse that could only em­power man’s cre­ativ­ity if it were a uni­verse of in­tel­li­gent de­sign. GLENDA CAR­ROLL Bun­damba
