Answer:
radio waves
microwaves
The wavelength of the radio wave is 5.5 × 10³ m. If the frequency of the wave is 5.5 × 10⁴ hertz and the speed of the wave is 3.0 × 10⁸ m/sec.
The speed(v) of a wave is the product of wavelength(λ) and the frequency(η). We can understand this relation by the definition of the speed, which is the distance travelled by the object in unit time. The unit of distance is meter, also the unit of the wavelength is meter. On the other hand the unit of frequency is sec⁻¹. So,
Speed of a wave(v) = wavelength(λ) × Frequency(η)
Wavelength(λ) = speed of the wave(v)/Frequency(η)
Wavelength(λ) = (3.0 × 10⁸)/(5.5 × 10⁴)
Wavelength(λ) = 5.5 × 10³ m

bank teller

heart surgeon
Answer:
Furniture mover.
Explanation:
A strain is a soft tissue injury that happens on the muscle or tendon - it could occur on several parts of the body, such as hands or legs. When it is acute, an incident might have caused it and proper rest would let it heal.
This type of injury could happen to athletes, but those who are at risk are those who are involved in sports field such as wrestling and football. Thus, baseball players are a lower risk.
Bank tellers and heart surgeons would not suffer from this type of injury - they are more likely to suffer from chronic than acute strains do to the overuse of certain muscles.
The group that is at the highest risk are people who move heavy objects - such as furniture mover.
