What is the wavelength of light in water if it has a frequency of 7.8 1014 Hz?
What will be an ideal response?
3 x 10^8/7.8 x10^14
3/7.8=0.3846
10^8/10^14=10^-6
3.8 x 10^-7- in standard form
converting factor 10^9
water=1.33
3.8 x10^-7 x 10^9= 380
380/1.33
Answer= 286 nm

Radioactive Decay: Two radioactive isotopes, X and Y, both decay to stable products. The half-life of X is about a day, while that of Y is about a week. Suppose a radioactive sample consists of a mixture of these two nuclides. If the mixture is such that the activities arising from X and Y are initially equal, then a few days later the activity of the sample will be due
A. predominantly to Y. B. predominantly to X. C. entirely to Y. D. to X and Y equally.
