Datrys pi/frac{1{lambda}/eta}(tau

$$\frac { \pi } { \frac { 1 } { \lambda } / \eta } ( \tau$$

Enrhifo

$$\pi \eta \lambda \tau$$

Camau Ateb

Rhannwch \pi â \frac{\frac{1}{\lambda }}{\eta } drwy luosi \pi â chilydd \frac{\frac{1}{\lambda }}{\eta }.

$$\frac{\pi \eta }{\frac{1}{\lambda }}\tau$$

Rhannwch \pi \eta â \frac{1}{\lambda } drwy luosi \pi \eta â chilydd \frac{1}{\lambda }.

$$\pi \eta \lambda \tau$$

Gwahaniaethu w.r.t. λ

$$\pi \eta \tau$$
