Can someone plz me on question 3 i really need plz

1.Describe

Frequency (f) and wavelength (λ) are inversely related.

f ∝ 1/λ

As one goes up, the other goes down and vice versa.

2.Infer

The frequency of infrared light is less than that of red light, so infra could mean something like less than or below or beneath.

Ultrahigh frequencies are extremely high compared with those of visible light. Ultrasound has frequencies that are far beyond what we can hear. An ultracentrifuge goes at extremely high speed, and an ultramicroscope can “see” tiny structures. Ultra could probably mean something like extremely or far beyond.

3.Analyze

Energy is directly proportional to frequency (E ∝ f).

Frequency is inversely proportional to wavelength (f ∝ 1/λ).

Energy is inversely proportional to wavelength (E ∝ 1/λ).
