Answer:

1. Wave period = 0.962 s

2. Will absorb red and blue and reflect green

Explanation:

1.

The wave period is:

T = \frac{\lambda }{v} \\Where: \\T: Wave period \\ \lambda : Wavelength \\v: velocity

Wavelength is the distance between crests. So replacing the given information:

T = \frac{2.50}{2.60} = 0.962 s\\

2. In simple words the color of an object is the light it reflects. A green object reflects green light, and the rest is absorbed (red and blue).

Answer:

1) Period of wave motion = T = 0.9615 s

2) Green object will absorb red (Long wavelength) and blue (short wavelength) and will reflect green.

Explanation:

First Part:

Distance between two crests = wavelength = λ = 2.50 m

Speed of the waves = v = 2.60 m/s

We know that,  

v = f λ

v = λ/T

T = λ/v   ……… (i)

By putting values in equation (i),

T = 2.50/2.60

T = 0.9615 s

Second part:

When an object absorbs red and blue colors, it appears green. Green object will always reflect green color making it appear green.

5280 feet to meters
lesya [120]

Answer:

1m= 3.2 feets

? = 5280 feets

let ? be n

cross multiply

3.2n = 1×5280

n= 5280÷3.2

n= 1650

so, 5280 feets is equal to 1650 metres
