Answer

Explanation:

Step1: Analyze frequency values

Looking at the frequency scale, gamma - rays have the highest frequency ($10^{20}$ Hz) and radio - waves have the lowest frequency ($10^{4}$ Hz).

Step2: Analyze wavelength values

From the wavelength scale, radio - waves have the longest wavelength ($10^{3}$ m) and gamma - rays have the shortest wavelength ($10^{-12}$ m).

Step3: Recall relationship

The relationship between frequency ($f$) and wavelength ($\lambda$) in the electromagnetic spectrum is given by $c = f\lambda$, where $c$ is the speed of light. So, frequency and wavelength are inversely proportional.

Step4: Identify wave type by wavelength

A wavelength of $10^{-3}$ m falls within the microwave range.

Step5: Identify wave type by frequency

A frequency of $10^{4}$ Hz is in the radio - wave range.

Step6: Objects for $10^{-5}$ m wavelength

Infrared waves have a wavelength around $10^{-5}$ m. Objects that use infrared include remote controls and night - vision goggles.

Step7: Objects for $10^{8}$ Hz frequency

Microwaves have a frequency around $10^{8}$ Hz. Objects that use microwaves include microwave ovens and some wireless communication devices.

Answer:

  1. Gamma - rays have the highest frequency; radio - waves have the lowest frequency.
  2. Radio - waves have the longest wavelength; gamma - rays have the shortest wavelength.
  3. Frequency and wavelength are inversely proportional ($c = f\lambda$, where $c$ is the speed of light).
  4. Microwave.
  5. Radio - wave.
  6. Remote controls, night - vision goggles.
  7. Microwave ovens, some wireless communication devices.
