Answer:
3.2m
Explanation:
Given parameters:
Frequency of the FM radio = 9.23 x 10⁷Hz
Velocity of the waves = 3 x 10⁸m/s
Unknown:
Wavelength of the wave = ?
Solution:
To solve for the wavelength of the wave, we need the velocity equation;
Velocity = frequency x wavelength.
Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.
Since the unknown is wavelength, we solve for it:
3 x 10⁸ = 9.23 x 10⁷ x wavelength
wavelength =
wavelength = 3.2m
Answer:
sunlight in deeper location decreases
Explanation:
because the more salinity water has the harder it is to see and the harder it is for light to travel through the ocean
Answer:
length of rope is 13.04 feet
Explanation:
Given data
high = 7 feet
from the bottom = 11 feet
to find out
length of rope
solution
we use here Pythagorean Theorem
we know length of rope is here hypotenuse
so h² = 7² + 11²
so h =
h =
h = 13.038 ft
so length of rope is 13.04 feet
Answer:
the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
Explanation:
A microscope uses a mirror to reflect light to the specimen under the microscope. ... An astronomical reflecting telescope uses a large parabolic mirror to gather dim light from distant stars. A plane mirror is used to reflect the image to the eyepiece.
