A soap bubble is 115 nm thick and illuminated by white light incident perpendicular

The  wavelength is and the color is  Orange

Explanation:

from the question we are told that  

     The thickness is

      The refractive index of water is  

Generally the condition for constrictive interference is  

Where   is the wavelength of light in a particular medium

  Now considering the medium of water(soap bubble )

 The  wavelength of light in this medium is mathematically represented as

So  

=>    

substituting values  

The color is orange because the wavelength range of yellow is  

       590–625 nm

7 minutes / 7 minutos

No hablo español pero

el solucion es

Explanation:

por explanacion :

tiempo, t = ?

distancia, d =89.66km

velocidad, v =756.66 km/h

v = d/t

vt = d

t = d/v

t = 89.66/756.66

= 0.12 hours/horas

tiempo en minutos = 0.12 × 60

= 7 minutos / minutes
