I'm in my mid 20's and the girl's 2 years younger than I am. We knew each other on Tinder a week back and have since exchanged number very causally and indirectly. We texted back and forth every single day and had a lot of dynamics. We had dinner today and I was cracking a lot of jokes on her. We chilled together (without alcohol) somewhere and she asked "what are we doing later". Was she subtly hinting sex or is this some post-April fool's?

• ### Wien's law?

In an experiment to study a black body radiator, the intensity of emitted radiation is measured as a function of the wavelength of the radiation. At a particular temperature T1 the wavelength of the highest intensity radiation is determined to be λ1.

In an experiment to study a black body radiator, the intensity of emitted radiation is measured as a function of the wavelength of the radiation. At a particular temperature T1 the wavelength of the highest intensity radiation is determined to be λ1. When the temperature is changed by ∆T the wavelength of the highest intensity radiation changes to λ2, with λ2 = 0.9λ1. The relationship between T1 and ∆T is: A. not possible to determine because of the ultra-violet catastrophe. B. T1 = 9∆T Kelvin C. T1 = 10/9∆T Kelvin D. T1 = 0.111∆T Kelvin E. None of the above Some explanation would be good. I have tried Wien's law but it didn't work.
