Open the PhET simulation Waves Intro. Choose Light. Set the Frequency and Amplitude sliders in the middle. Select multiwave and top view. Your screen should look like the image below.
-Click on the green button, what color is the light?
2. Move the frequency slider all the way to the left (a lower frequency), describe how decreasing frequency changes the color.
3. Describe how decreasing frequency changes the distance between the waves (wavelength).
4. Move the frequency slider all the way to the right (a higher frequency), describe how increasing the frequency changes the color.
5. Describe how increasing the frequency changes the wavelength
What is the longest focal length lens that will work?
Heat is extracted from a certain quantity of steam at 100 degrees celsius. Thus the steam changes into ice at 0 degrees celsius. If this energy were used to accelerate the ice from rest, what would be the linear speed of the ice.
The asymptotic wavelength
A woman with mass of 55 kg stands at the rim of a horizontal table having a moment of inertia of 410 kg m2 and a radius of 1.6 m. How much work does the woman do ON THE TABLE to set it into motion
A charge +q is located at the origin, while an identical charge is located on the x axis at x = +0.50 m, Where should the third charge be located
An object is solid throughout when the object is totally submerged in ethyl alcohol its apparent weight is 15.2 N when completely submerged in water its apparent weight is 13.7 N what is the volume of the object
The area enclosed by the wire loop in the figure below is reduced from 31 cm2 to 13 cm2 in a time interval of 0.13 s. Find the emf induced in the wire
The engine delivers 265 hp to an aircraft propeller at 2190 rpm. Determine how much torque does the aircraft engine provide
Two 10.0 cm -diameter electrodes 0.52 cm apart form a parallel-plate capacitor. What is the charge on each electrode after insulating handles are used to pull the electrodes away from each other until they are 1.3 cm apart
A pitcher pitches a baseball of mass 0.20 kilogram. Find the magnitude of the change in momentum of the baseball
The force on the hanging rope is (let's take the downward directon as positive): F = m g - 18 N But this has to equal m*a by Newton's second law and we know that a = 3 m/s^2. m g - 18 N = m*(3 meters/s^2) ---> m = 18 N/[g - 3 m/s^2] = 2.64 kg
A boy of mass 37.9 kilogram jumps off a diving platform 1.61 meter high. Find the magnitude of the resistive force of the water on the boy
