Answer 1

Answer:

$\large \blue{ \underline{answer}} \\ \\ \large \implies{5 \times 10 {}^{14}hz } \\ \\ \large \implies \green{ \underline{explanation }} \\ \\ \large \implies{in \: \: the \: \: formula \: } \\ \\ \large \implies{v \: = \frac{c}{ \lambda} } \\ \\ \large \implies{c \: = \: velocity \: \: of \: \: light} \\ \\ \large \implies{c \: = \: 3 \: \times \: 10 {}^{8}m s } \\ \\ \large \implies{ \lambda \: = \: 6000 \: \: angstrom } \\ \\ \large \implies{6000 \times 10 {}^{ - 10} m \: = 6 \times 10 {}^{ - 7} } \\ \\ \large \implies{1 \: angstrom \: = \: \: 1 \times 10 {}^{ - 10}m } \\ \\ \large \implies \therefore{ \: \: c \: = \frac{3 \times 10 {}^{8} }{6 \times 10 {}^{ - 7} } } \\ \\ \large \implies \therefore \orange{ \boxed{ \: \: \: c \: \: = \: \: 5 \times 10 {}^{14}hz }}$
