Question

Calculate the frequency of wavelength = 357 nm light.

Type in the numeric part of your question to the nearest THz. E.g., if your answer is f = 8.87 × 10 14 H z, then type in 887.

When a running football player “throws” his right foot down and behind him, as in this sketch,

what happens in reaction is:

It is easier on your car if you stop by plowing into a deep snow drift than if you stop by plowing into a brick wall (ouch). This is because...

Group of answer choices

The ground pushes up and forward.

He begins to fall backward.

The ground exerts no force on him.

Counter-rotational torque applies.

Answer 1

---->

Given that,

Given: wavelength ($\lambda$) = 357 nm = 357 x 10^-9 m

Since: Frequency (f) = c / $\lambda$

= (3 x 10⁸ m/s) / (357 x 10^-9 m)

= 840.33 x 10¹² Hz

= 840.33 THz
