varepsilon=hc/lambda=663*10^-34*3*10^8/500*10^-9= шешу

$$\varepsilon = \frac { h c } { \lambda } = \frac { 663 \times 10 ^ { - 34 } \times 3 \times 10 ^ { 8 } } { 500 \times 10 ^ { - 9 } } =$$

Есептеу (complex solution)

$$\epsilon =\frac{ch}{\lambda }\text{ and }\frac{ch}{\lambda }=\frac{1989}{50000000000000000000}$$

λ теңдеуін шешу

$$\lambda =\frac{50000000000000000000ch}{1989}$$

$$\epsilon =\frac{1989}{50000000000000000000}\text{ and }c\neq 0\text{ and }h\neq 0$$

ε теңдеуін шешу

$$\epsilon =\frac{1989}{50000000000000000000}$$
