A) The active element of a laser is made of a glass rod 25.0 cm long and 1.40 cm in diameter. Assume the average coefficient of linear expansion of the glass is equal to9.00 10-6 (°C)−1. The temperature of the rod increases by 64.0°C. i) What is the increase in length? I worked this out to be 25.0144cm but doesn't sound right given its original length is 25cm exactly. ii) What is the increase in its diameter? iii) What is the increase in its volume? Can someone pls run me through the working for these three questions.
