1) Measurement Focal length of Convex lens
- Parallel light law
- Auto collimation law
- Measurement law using collimator
- Measurement focal length by thin lens equation
- Measurement focal length using magnifi
idea behind the sonic resonance test method can be explained using the equation by which one can measure the propagating speed of flexural sonic wave through a medium
(1)
where v is the propagating speed of the flexural wave on a string, F is the tension applied to both sides of the string, P is the mass per unit length of the string.
Some methmatical manipulation of Eq (1) yields
1. Plot the 1-D temperature profile with analytical solution
(temperature vs fin length)

Fin의 미소면적에 대해 대류에 의한 열의 손실을 고려하여 열전달식을 세워 보면,
---------- (1)
한편 미소변화량은 다음과 같이 나타낼 수 있다.

1. Respiration(호흡)
<호흡의 필요성에 대한 부정적 견해>
- 호흡에 대한 특별한 치료가 필요치 않다 (Darley, Aronson, Brown, 1975).
(말산출을 위해 필요한 호흡은 많지 않고 발성, 공명, 조음을 하는 valve 기능을 증가시 키는 것이 기류를 효과적으로 사용하도록 촉진시키기 때문)

Idealizing his/her partner
Exaggerating partner's virtue and explaining away their flaws
This behavior, often observed between newly smitten lovers, is called
"pink lens effect"
